Step-by-step explanation:

0.256256256...

Set up two equations:

x = .256256...

1000x = 256.256256...

Subtract them:

1000x = 256.256256... -  x = .256256... =

999x = 256

Solve for x:

999x = 256

x = 256/999

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

5x+40

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
