Answer:
51
Explanation:
According to PEMDAS, the first step would be to take care of the exponents. -7 times -7 is positive 49, so the equation would look like this:
11+49-9 From there, just add and subtract as normal!
60-9
Hope this helps!
11+(-7)^2-9 would be
11+49-9 (49 because 7^-2 = 49)
60-9 = 11
