Question

evaluate and find the answer... see the attachment for seeing the ques, plz help me!!​

Answer 1

512 = 8×64 = 2³×2⁶ =2^(3+6) =2⁹

512ⁿ = (2⁹)ⁿ =2⁹ⁿ

512ⁿ×2² = 2⁹ⁿ×2² = 2^(9n+2) =2^5

9n+2=5

9n =3

n= 3/9 =⅓

Answer 2

Answer:

(512)n × 2² = 2⁵

=> (512)n = 2⁵ ÷ 2²

=> (512)n = 2⁵-²

=> (2⁹)n = 2³

=> 9n = 3

=> n = 3/9

=> n = 1/3

hope it helps you!!
