3-6.

Use what you have learned about exponents to rewrite each of the expressions below.

1.  $\frac { h ^ { 9 } } { h ^ { 11 } }$

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

$\frac{1}{h^2}$

1.  $x^3\cdot x^4$

• How many factors of $x$ are multiplied together?

$x^7$

1.  $(3k^5)^2$

• Write $3k^5$ twice and then follow the pattern from part (b).

$(3k^5)(3k^5)$

1.  $n^7\cdot n$

• Refer to part (b).

1.  $\frac { 16 x ^ { 4 } y ^ { 3 } } { 2 x ^ { 4 } }$

• $\frac{16y^3}{2}=8y^3$

1.  $4xy^3\cdot7x^2y^3$

• Refer to part (b).

$28x^3y^6$
