3-98.

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 $y$?

$(x^2·x^2)(y^3)=x^4y^3$

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.

$(x^2·x^4)(2·−3)=−6x^6$

1. $(2x)^3$

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