Make x subject of formula in a√x-1=b

Answer 1

To make x the subject of the formula in a√x-1=b, we can follow these steps:

1. Add 1 to both sides of the equation to isolate the term with the square root:
a√x = b + 1

2. Divide both sides of the equation by a to eliminate the coefficient in front of the square root:
√x = (b + 1) / a

3. Square both sides of the equation to remove the square root:
(√x)^2 = ((b + 1) / a)^2

Simplifying:

x = ((b + 1) / a)^2

Therefore, x is the subject of the formula and is equal to ((b + 1) / a)^2.
