x= √144
B)
x=V12
X=-
-V144
D)
x = 1V144

Answer 1

Explanation:

f the 2s are exponents, you need to indicate this with "^":

x^2 = 144^2 means x² = 144²

x = ±√144² = ±144

Answer 2

Explanation:

If the 2s are exponents, you need to indicate this with "^":

x^2 = 144^2 means x² = 144²

x = ±√144² = ±144
