Question

Решите уравнение (1/2)^3-2x=8

Answer 1

(0,5)^(3-2x)=8                                                                                                          

( 0,5)^(3-2x)= ( 0,5)^(-3) 

3-2x= -3

2x=6

x=3

                                                                                      

Answer 2

(1/2)(1/2)(1/2)=1/4(1/2)=1/8=0.125

0.125-2х=8
-2х=0.125-8
-2х=-7,875
х=3.9375

Answer 3

To solve the equation (1/2)^3 - 2x = 8, follow these steps:

Step 1: Simplify the left-hand side of the equation. (1/2)^3 is equal to (1/2)(1/2)(1/2) = 1/8. So the equation becomes: 1/8 - 2x = 8

Step 2: Get rid of the constant term on the left side by moving it to the right side of the equation. Subtract 1/8 from both sides: -2x = 8 + 1/8

Step 3: Combine the constants on the right side. -2x = 65/8

Step 4: Solve for x by dividing both sides by -2. x = (65/8) / -2

Step 5: Simplify the result. x = -65/16

So the solution to the equation is x = -65/16.
