Answer 1

Answer:

-14/3

Step-by-step explanation:

if a = -4, then replace your a with -4, making it -4 to the second power. b = 2, so replace b with 2 and solve with "pemdas."

(If you don't know what pemdas is, it the order of operation which goes parentheses, exponents, multiplication, division, addition, and subtraction.

First solve your exponent, which is -4 to the second power. A negative time a positive would be a negative, and -4 to the second power is -16.

-16 + 2 = -14, leaving you with -14/3

Answer = -14/3

Answer 2

Substitute a for (-4) and b for (2)
The expression will be
[(-4)^2 + 2]/3
(16 + 2) /3
18/3
6
The answer will be: 6
