Question

Simplify 15y^-7/18y^-3 Assume y≠0

Answer 1

The first step for simplifying the above fraction is to divide the terms with the same base by subtracting their exponents. 
$\frac{15}{18y^{-3-(-7)} }$
Remember that when there is a "-" sign in front of the parenthesis,, we need to change the sign of each term in the parenthesis. This changes the fraction to the following:
$\frac{15}{18y^{-3+7 } }$
Calculate the sum of the exponents.
$\frac{15}{18 y^{4} }$
Lastly,, reduce the fraction with 3 to find your final answer.
$\frac{5}{6 y^{4} }$
