its basically saying \[-7 \times -7\]

Answer 3

if the power is 2, 4 and so on, the - dissapears. And you just square the 7 . Or -7 to the power of 2 is basically (-7 * -7), for example 2 to the power of 3 would be ( 2*2*2)

Answer 4

$$\huge -7^2=-(7•7)$$

try putting it into a calculator..it should come out as 49, a negative multiplied by another negative gives you a positive. \[-7 \times -7=49\]

Think of $$-x^2$$ with 7 in place of x.
