If (7²)x = 1 what is the vaule of x

x=4

Step-by-step explanation:

1 Add 11 to both sides.

2x=7+12x=7+1

2 Simplify  7+17+1  to  88.

2x=82x=8

3 Divide both sides by 22.

x=\frac{8}{2}x=

2

8

4 Simplify  \frac{8}{2}

2

8

  to  44.

x=4x=4

cheek:

1 Let x=4x=4.

2\times 4-1=72×4−1=7

2 Simplify  2\times 42×4  to  88.

8-1=78−1=7

3 Simplify  8-18−1  to  77.

7=7 7=7

(or -3)

x=1/49

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Add  1  to both sides of the equation :  

                     49x = 1

Divide both sides of the equation by 49:

                    x = 1/49 = 0.020

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
