If \( \Large a^{2x+2} = 1 \), where a is a positive real number other than 1, then x = ?


A) -2

B) -1

C) 0

D) 1

Correct Answer:
B) -1

Description for Correct answer:

Given that, \(  \Large  a^{2x+2} = 1 \)

=> \(  \Large  a^{2x+2} = a^{0} \)

=> \(  \Large  2x + 2 = 0 \)

=> \(  \Large  x = \frac{-2}{2} = -1 \)
