Exercise 1 Page 348

To simplify the given expression, we will use the Properties of Exponents. For this exercise, we will begin by multiplying powers with the same base. Let's do it!

y^3* y^(- 5)

MultPow

a^m*a^n=a^(m+n)

y^(3+(- 5))

AddNeg

a+(- b)=a-b

y^(- 2)

NegExponentToFrac

a^(- m)=1/a^m

1/y^2
