Question 84830
So this question seems to be saying the following:

{{{(-4-sqrt(49)+5)^2}}}

To begin solving this problem, what we first want to do is solve what is simplfy what is inside the parenthesis. So the first thing we can do is take the square root of 49 to get the following:

{{{(-4-7+5)^2}}} 

Now what we can do is again simplfy inside the parenthesis and perform the operation of -4-7+5 to get:

{{{(-6)^2}}}

And finally we would square -6 which means we do {{{(-6)(-6)}}} to get the final answer as:

{{{36}}}
