How do you simplify 13-2*5/(4-7)^2

Answer 1

The answer is 45. Here is my work.

Answer 2

Subtract 7 from 4 to get -3.
13-2*(5)/((-3)^(2))

Multiply -3 by -3 to get 9.
13-2*(5)/(9)

Multiply -2 by (5)/(9) to get -(10)/(9).
13-(10)/(9)

Combine 13-(10)/(9) into a single expression by finding the least common denominator (LCD). The LCD of 13-(10)/(9) is 9.
(107)/(9)
