Remember the following:-ve * -ve = +ve
-ve * +ve = -ve
x² = x * x
x⁻² =
Now, for the given:1- If the given equation is -(7)², then:-(7)² = - (7*7) = -49
Therefore,, -49 would make this statement true.
2- If the given equation is (-7)², then:(-7)² = (-7) * (-7) = 49
Therefore, 49 would make this statement true
3- If the given equation is 7⁻², then:7⁻² =

Therefore,

would make the statement true.
Hope this helps :)
