Question

if (8^x) - 4= 0,x=?​

Answer 1

Answer:

8^x-4=0

8^x=4

2^x+3=2^2

equating powers

x+3=2

x=-1

Step-by-step explanation:

Answer 2

Answer:

2/3

Step-by-step explanation:

8^x = 4

(2^3)^x=2^2

2^3x = 2^2

since we have same bases therefore powers must also be same powers

=> 3x = 2

x = 2/3
