Can anyone help me ? Which ones do I click ?

4 and -4

Step-by-step explanation:

n^-2 = 1/16

Negative power rule:

(4)^-2 = 1/4²

= 1 /16

(-4)^-2= (-1)²/4²

= 1 /16

3(m + 5 + 9m)

A.
(1) 3m + 15 + 27m
(2) 3(10m + 5)

B. 3(m + 5 + 9m)distributive property
     (3 * m) + (3 * 5) + (3 * 9m) =
    3m +  15 + 27m

C. 3(m + 5 + 9m) = 3(10m + 5)m = 1
     3(1 + 5 + 9(1) = 3(10(1) + 5)
     3(1 + 5 + 9) = 3(10 + 5)
     3(15) = 3(15)
     45 = 45
