The value of given expression when m = 3 is 27
<h3><u>Solution:</u></h3>Given expression is
We have to evaluate the given expression for m = 3
To find for m is equal to 3, substitute m = 3 in given expression
From given expression,
Plug in m = 3 in above expression
------ eqn 1
We know that,
can be expanded as,
Applying this in eqn 1, we get
Simplify the above expression
Therefore, for m = 3 we get,
Thus value of given expression when m = 3 is found
