Question

simplify the expression (7-(-1*-1)+(-2*-2) Tip: to raise -2 to the second power write (-2)(-2).
A. 68
B. 60
C. 40
D. 32

Answer 1

first, the parens are not balanced.
second, I don't see any powers.
third, (-2) to the power -2 is not (-2)(-2). That is (-2)^2

Without some major cleanup, I see no way to get any of the choices.

Answer 2

its 68
