Question

2 power x-1 plus 4 power x is equal to 8

Answer 1

Answer:

Step-by-step explanation:

(2)^x × (4)^x = (8)^1/3 × (32)1/5

=>2^x × (2^2)^x = (2^3)^1/3 × [(2)^5]^1/5

=>2^x × 2^2x = 2 × 2

=> 2^(2x + x) = 2^2

Since base on both sides is equal hence we now equate the powers

2x + x =2

3x =2

x =2/3
