Basically the question is,
An efficient computational model for converting a natural number from a non-decimal base to decimal, known as Horner's method is illustrated in the following example:

6253 (with an increasing power of 8, just right under bottom of number 3) = ( ( 6 x 8 +2 ) x 8 + 5 ) x 8 + 3 = 3243 (with an increasing power of 10, just right under bottom of number 3).
In words multiply the first digit by the base, add the second digit, multiply by the base, add the third digit, multiply by the base , and so on.The final step is to add the last digit.

Use Horner's method to convert the following numbers to decimal.
a) 7216 (with an increasing power of 8, just right under bottom of number 6) (you cant put those symbols on keyboard like the 8 number symbol) answer is: 3726 with a 10 like i said
b) 543517 (with an increasing power of 8, just right under bottom of number 6) (you cant put those symbols on keyboard like the 8 number symbol) answer is : 182095 with a 10 like i said
c) 8CB2 (with an increasing power of 16, just right under bottom of number 2) (you cant put those symbols on keyboard like the 16 number symbol) answer is 36018 with a 10 like i said
D) E490DF (with an increasing power of 16, just right under bottom of number 2) (you cant put those symbols on keyboard like the 16 number symbol) answer is 14979295 with a 10 like i said

PLEASE HELP! show working because i need to understand these problems and the answers do not show how to solve them!

i have attached a image of the question just incase no one understands

What are your thoughts? What have you done so far? Please show us your work even if you feel that it is wrong so we may try to help you. You might also read

Some things to ponder:

Are you assuming a parallel computer or a serial one? Everyone is used to binary representation of numbers on a computer that they forget there are other possibilities. So, does your computer work in the usual binary or is it special in some way?

Hints:

On a computer, all numbers are integers [or pair of integers]. Thus, the range of numbers is limited by two things, mantissa and exponent. So, do you need some exception handling?

Division is very expensive compared to multiplication which is expensive compared to add/subtract/bit shift. So, conversion to a text (string) structure and 'popping' digits might be the way to go?

Some times it is better 'work backwards', which makes the Horner's method efficient.

I'm sorry, but the policy you saw in the "Read Before Posting" announcement remains in effect; namely, we don't "do" students' work for them, nor do we hand out the answers. Whoever told you that this is one of those "cheetz" sites was very much mistaken. :shock:

The text of your sideways (and thus quite-difficult-to-read) attachment appears to be as follows:

Assignment G2/2 . . . . . . . . . . .(From Grossman Chapter 2)

7. An efficient computational model for converting a natural number from a non-decimal base to decimal, known as Horner's method, is illustrated in the following example:

. . . . .\(\displaystyle 6253_8\, =\, \bigg(\, \left(\, 6\, \times\, 8\, +\, 2\, \right)\, \times\, 8\, +\, 5\, \bigg)\, \times\, 8\, +\, 3\, =\, 3243_{10}\)

In words: multiply the first digit by the base, add the second digit, multiply by the base, add the third digit, multiply by the base, and so on. The final step is to add the last digit.

Use Horner's method to convert the following numbers to decimal:

(a) 7216₈ . . .(b) 543517₈ . . .(c) 8CB2₁₆ . . .(d) E490DF₁₆

9. Convert the following decimal numbers to octal:

(a) 3842₁₀ . . .(b) 291.9375₁₀

10. Convert the following decimal numbers to hexadecimal:

(a) 29803₁₀ . . .(b) 6962.578125₁₀

6253 (with an increasing power of 8, just right under bottom of number 3)

What do you mean by "an increasing power of 8", when you are referring to the base of the number? (A "power" is something very much different.)

PLEASE HELP! show working because i need to understand these problems and the answers do not show how to solve them!

As you read in the announcement, we cannot here provide hours of classroom instruction. While it is unfortunate that you missed the chapter on this topic when your instructor was covering it in class, we can only help you once you've learned the basic background terms and techniques.

This topic is not about "powers" or "exponentials", but about "number bases". The terms "decimal", "octal", and "hexadecimal" all refer to number bases (being base-ten, base-eight, and base-sixteen, respectively). You can study online lessons such as this, among the many other lessons found by searching useful keywords.

Once you have studied at least two online lessons, please attempt the exercises. If you get stuck, you can then reply with a clear listing of your thoughts and efforts so far, at which point we can begin to work with you.

Thank you!
