Given the expression:

-4^2

we know:

$4^2 = 4 \times 4 = 16$

then;

-4^2 = -16

Therefore, the value of expression -4^2 is -16 i.e negative.

(-4)^2

we know:

$4^2 = 4 \times 4 = 16$

(-1)^2 = 1

then;

$(-4)^2 = (-1)^2 \cdot (4)^2= 16$

Therefore, the expression (-4)^2 is 16 i.e Positive.

4^2

we know:

$4^2 = 4 \times 4 = 16$

then;

4^2 = 16

Therefore, the expression 4^2 is 16 i.e Positive.
