Question

What Values of X will make x2 (Exponent of 2) =16 true? HELPPPPPP!!

A)4 AND -4
B)2
C)4
D)6 AND -6

Answer 1

A

Explanation:

Given

x² = 16 ( take the square root of both sides )

`√(x^2)` = ±
`√(16)` ← note plus or minus sign

x = ± 4

Since 4² = 4 × 4 = 16 and

(- 4)² = - 4 × - 4 = 16
