Question

How do you Find value?

Answer 1

`b=(3)/(4)`

Step-by-step explanation

We want to find the value of b in:

`b^2=(36)/(64)`

To do this, we find the square root of both sides of the equation and simplify.

That is:

`\begin{gathered} \sqrt[]{b^2}=\sqrt[]{(36)/(64)} \\ \Rightarrow b=\frac{\sqrt[]{36}}{\sqrt[]{64}} \\ b=(6)/(8) \\ \Rightarrow b=(3)/(4) \end{gathered}`

That is the value of b.
