Answer:
(-13)^2= (15* -11 + -4) = -169
Explanation:
Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign
because1 x −1 = −1
(−13)^2=15 x −11 −4
Raise − 13 to the power of 2 .
169=15 x −11 −4
Multiply 15 by −11.
169 = −165 − 4
and finally Subtract 4 from−165.
169 = −169
if its (-13)^2 / (15*-11+-4) as the orginal post did not say divided, the answer would be -1 hope his helps.
