## Algebra: A Combined Approach (4th Edition)

Using order of operations, solve the numerator and denominator separately; first solve exponents, then multiply, and then add and subtract. $\frac{15 + (-4)^{2} + |-9|}{10 - 2 * 5}$ = $\frac{15 + 16 + |-9|}{10 - 2 * 5}$ = $\frac{15 + 16 + |-9|}{10 - 10}$ = $\frac{15 + 16 + 9}{10 - 10}$ = $\frac{40}{0}$ = undefined, you cannot divide by 0.
