Question

(0,8)^3-2х = (1,25)^3

Answer 1

(8/10)^(3-2х)=(10/8)^3
(10/8)^(2x-3)=(10/8)^3
2x-3=3
2x=6
x=3

Answer 2

To solve the equation:

(0,8)^3 - 2x = (1,25)^3

Let's simplify the equation step by step:

(0.8)^3 - 2x = (1.25)^3

0.512 - 2x = 1.953125

Now, let's isolate the term with x on one side of the equation:

-2x = 1.953125 - 0.512

-2x = 1.440125

To solve for x, we need to divide both sides of the equation by -2:

x = 1.440125 / -2

x = -0.7200625

Therefore, the solution to the equation is x = -0.7200625.
