Question

solve it also please..... ​

Answer 1

Answer:

5/2

Step-by-step explanation:

4^x - 4^(x-1) = 24

4^x - 4^x /4 = 24

4^x( 4 - 1) = 24 × 4

4^x = 24 × 4/3 = 32

4^x = 32

(2^2)^x = (2^5)

2^2x = 2^5 => 2x = 5 => x = 5/2

Answer 2

Ans is 3!

4^x-4^x-1=24

4^x(1-1/4)=24

4^x(3/4)=24

4^x=24*4/3

4^x=32

4^x=4^3

x=3
