Is this correct ?

[Rohan]

Anyone out there, please check my answers.

Thank you for your pm .... just read it toninght, and I checked it again you are correct it is multiply and not a variable.

Convert the following numbers to denary (base 10):

1) 736_8 (that's 736, base-8)
2) DE1_16 (that's DE1, base-16)

I have redone them, hope they are correct now, could you please check and let me know, if my answers are correct ? If it is not correct please tell me how you worked it out.

Answers :

1) 3782
2) 3505

Hello, Rohan!

Do you understand anything about Number Bases?

Convert the following numbers to base 10:

\(\displaystyle 1)\;736_8\)

We have: \(\displaystyle \,7\cdot8^2\,+\,3\cdot8\,+\,6\:=\:478\)

\(\displaystyle 2)\;DE1_{16}\)

Assuming that: \(\displaystyle A\,=\,10,\:B\,=\,11,\:C\,=\,12,\\,=\,13,\:E\,=\,14,\:F\,=\,15\)

We have: \(\displaystyle \,13\cdot16^2\,+\,14\cdot16\,+\,1\;=\;3553\)
