Question

If 2³+2x=2⁴,then x equals.

Answer 1

$2^{3}+2x=2^{4}\\ \\ 2x=2^{4}-2^{3}\\ \\ 2x=2^{3}(2-1)\\ \\ 2x=2^{3}=8\\ \\ x=\frac{8}{2}\\ \\ x=4$

Answer 2

Given : The given equation is, 2³+2x=2⁴

To find : The value of x

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to solve the given equation to calculate the value of x)

Here, we will be using normal equation solving method.

On solving the given equation for variable x, we get :

2³+2x = 2⁴

2x = 2⁴-2³

2x = (2×2×2×2) - (2×2×2)

2x = 16 - 8

2x = 8

x = 8/2

x = 4

(This value of x, will be considered as the final result of the given mathematical problem.)

Hence, the value of x is 4
