Question

Simplify.
(y 3)5 · y 4
y12
y19
y32
y60

Answer 1

When you are multiplying an exponent by an exponent that is outside the parentheses you multiply the exponential values together (Remember the power rule (b^n)^m = b^(n*m)?). Then add the 4 (Remember product rules a^n*a^m = a^(n+m)?)


`( y^(3))^(5)* y^(4) = (y^(15) )* y^(4)= y^(19)`

Your answer is B. y^19
