Question

if 2^[x+3] = 4^[x-1] find the value of x......? Please solve this​

Answer 1

 2x + 3 = 4x - 1 => 2x + 3 - 4x = 4x - 1 - 4x => - 2x + 3 = - 1 => 2x - 3 = 1 => x = 4/2 = 2. Please mark brainliest. 5.0. 1 vote.

Answer 2

The correct answer is 5.

Given: The equation $2^{x+3} =4^{x-1}$.

To Find: The value of x.

Solution:

$2^{x+3} =4^{x-1}$

$2^{x+3} =2^{2(x-1)}$

As the base is equal so we can equate the powers also.

x + 3 = 2(x - 1)

x + 3 = 2x - 2

x = 5

Hence, the value of x is 5.
