Question 7

Describe how you would simplify the given expression.

Revolt · Accepted Answer

Simplify inside the parentheses by dividing coefficients, subtracting the exponents on like bases, and raising the resulting expression to the –3 power. Then, write bases with positive exponents. Equivalently, raise the numerator and denominator to the –3 power, multiply exponents using the power of a power property, divide coefficients, subtract exponents on like bases, and write with positive exponents. The simplified expression is y^15/(64x^24).
