integers, ordering, simplifying w/ exponents, poly. div.

[adpcane15]

1) Identify the integers: -8, -14/5, 2.3, Pi, √9, 0/8

2) Order from Smallest to Largest: √5, -4, l-7l, -l5l, l-4+9l, -Pi

3) Write without exponents: 3^-4

4) Simplify (a^4 b^-3 c^-5/a^2 b^5 c^-3)^-3

5) Divide: (27x^3 - 18x^2 + 6x - 12) / (3x^2)

I'm sorry to hear that none of these topics has been covered in your class or in your textbook. Unfortunately, we cannot reasonably provide the requested hours of instruction within this environment. So please consider studying a few of the many lessons available online.

1) Identify the integers: -8, -14/5, 2.3, Pi, √9, 0/8

To learn about number types (so you can figure out which of the above might be integers), try here:

. . . . .Google results for "number types"

2) Order from Smallest to Largest: √5, -4, l-7l, -l5l, l-4+9l, -Pi

I will guess that you're mostly asking about the absolute-value stuff, but maybe also about negatives and radicals...? Try here:

. . . . .Google results for "negative numbers"

. . . . .Google results for "absolute value"

. . . . .Google results for "square roots"

3) Write without exponents: 3^-4

4) Simplify (a^4 b^-3 c^-5/a^2 b^5 c^-3)^-3

These both rely on exponent rules. Try here:

. . . . .Google results for "exponents"

. . . . .Google results for "simplifying exponents"

5) Divide: (27x^3 - 18x^2 + 6x - 12) / (3x^2)

To learn about polynomials and how to simplify, try here:

. . . . .Google results for "polynomials"

. . . . .Google results for "dividing polynomials"

Once you have studied enough lessons to have learned the basic terms and techniques (give yourself a few hours, best done over a couple of days), please attempt the exercises. If you get stuck, or are unsure of your steps or solution, please reply showing all of your work and reasoning.

Thank you!
