Answer:
Given the expression:
1.
[tex]-4^2[/tex]
we know:
[tex]4^2 = 4 \times 4 = 16[/tex]
then;
[tex]-4^2 = -16[/tex]
Therefore, the value of expression [tex]-4^2[/tex] is -16 i.e negative.
2.
[tex](-4)^2[/tex]
we know:
[tex]4^2 = 4 \times 4 = 16[/tex]
[tex](-1)^2 = 1[/tex]
then;
[tex](-4)^2 = (-1)^2 \cdot (4)^2= 16[/tex]
Therefore, the expression [tex](-4)^2[/tex] is 16 i.e Positive.
3.
[tex]4^2[/tex]
we know:
[tex]4^2 = 4 \times 4 = 16[/tex]
then;
[tex]4^2 = 16[/tex]
Therefore, the expression [tex]4^2[/tex] is 16 i.e Positive.
