Question

Make t the subject of : b=9t²​

Answer 1

So the expression after making t the subject is:

$t=\frac{\sqrt{b}}{3}$

Further explanation:

In order to make a variable the subject of an equation, we have to isolate the variable on one side of the equation.

Given

$b=9t^2$

Here b is the subject of the formula.

To make t subject of the expression

$b=9t^2\\Dividing\ both\ sides\ by\ 9\\\frac{b}{9}=\frac{9t^2}{9}\\t^2=\frac{b}{9}$

Taking square root on both sides

$\sqrt{t^2} = \sqrt{\frac{b}{9}}\\t=\frac{\sqrt{b}}{\sqrt{9}}\\t=\frac{\sqrt{b}}{3}$

So the expression after making t the subject is:

$t=\frac{\sqrt{b}}{3}$
