Simplify each expression using the laws of exponents. Homework Help ✎

1. $(x^2)(x^2y^3)$

• How many factors of x are multiplied? How many of y?

• (x2 · x2)(y3) = x4y3

1. $\frac { x ^ { 3 } y ^ { 4 } } { x ^ { 2 } y ^ { 3 } }$

• Think about making ones and where any left over factors would remain.

• xy

1. $(2x^2)(−3x^4)$

• How many factors of x are multiplied?
Multiply the constants separately.

• (x2 · x4) (2 · −3) = −6x6

1. $(2x)^3$

• Write 2x three times and follow the pattern from part (a).
