So we have
(32)/( 7^(2) - 3^(2) )

Follow PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

So parentheses goes first. However, we have no parentheses so we must simplify the exponents first.


(32)/(49 - 9)

Now we simplify the denominator,

(32)/(40)

We can simplify this fraction by dividing 8 to the the numerator and denominator.

32 ÷ 8 = 4
40 ÷ 8 = 5

Our new fraction is 4/5 which, in decimal form, is 0.8

Hope this helps! :)
