10-61.

Recall that when you divide a number by itself, the quotient is 1. Can you find any factors that are in both the numerator and the denominator?

You can rewrite the expression.

$\frac{3\cdot3\cdot5\cdot5\cdot5\cdot8}{3\cdot5\cdot5\cdot5\cdot8}$

Since there are three 5's on the top and on the bottom, which may be canceled out. Similarly, there are 8's that will cancel and 3's that will cancel.

3

Rewrite the expression and simplify.

(3x)(3x)(3x)(3x)

81x4

You can rewrite this expression as:

$\frac{3^{3}3^{5}}{3^{2}}$
