Question

4^x+2^x+1=80. Solve it ​

Answer 1

Answer:

Step-by-step explanation:

Simplifying

4x + 2x + 1 = 80

Reorder the terms:

1 + 4x + 2x = 80

Combine like terms: 4x + 2x = 6x

1 + 6x = 80

Solving

1 + 6x = 80

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + 6x = 80 + -1

Combine like terms: 1 + -1 = 0

0 + 6x = 80 + -1

6x = 80 + -1

Combine like terms: 80 + -1 = 79

6x = 79

Divide each side by '6'.

x = 13.16666667

Simplifying

x = 13.16666667
