solve q no. 15 I will mark as wow person!!

Answer 1

Hey Friend ☺

4^2n - 1 - 16^n - 1 = 384

》4^2n - 1 - ( 4^2 )^n - 1 = 384

》4^2n - 1 - 4^2n - 2 = 384

》4^2n × 4^-1 - 5^2n - 4^-2 = 384

》4^2n ( 4^ - 1 - 4^ - 2 ) = 384

》4^2n ( 1/4 - 1/16 ) = 384

》4^2n ( 4 - 1 /16 ) = 384

》4^2n ( 3/16 ) = 384

》4^2n = 384 × 16/3

》4^2n = 128 × 16

》( 2^2 )^2n = 2^7 × 2^4

》2^4n = 2^11

4n = 11 .

》n = 11/4

Hope it helps you ..!!!
