Question

If 3(3^n) = 3, then the value of n is * option 1 - 3 option 2 - 0 option 3 - 1 option 4 - None of these

Answer 1

Step-by-step explanation:

=> 3(3^n) = 3

=> 3 * 3^n = 3

=> 3^( n + 1 ) = 3^1

Powers both must be equal.

=> n + 1 = 1

=> n = 1 - 1

=> n = 0

Identitiy used -

a^m * a^n = a^( m + n )
