If \( \Large 5^{5x+5}=1 \), then x equals
A) 0
B) -1
C) 1
D) \( \Large -\frac{4}{5} \)
Correct Answer:
B) -1
Description for Correct answer:
\( \Large 5^{5x+5} = 1 \)
\( \Large 5^{5x+5} = 5^{0} \left(a^{0}=1\right) \)
\( \Large \left[ \infty f\ bases\ are\ same\ then\ power\ are\ equal \right] \)
\( \Large 5x + 5 = 0 \)
5x = -5
x = -1
