Answer 1

Hello! I'm a physics student, here to help you out.
First off, let's read that ecuation:
\[8^{2}+9(\frac{ 12 }{ 3x2 })-7\]
My, this is clearly a arithmetic problem, so let's begin solving this, shall we?
Let's first get rid of that troublesome division:
we have to do that multiplication in the denominator first (the one below the line).
\[8^{2}+9(\frac{ 12 }{ 6 })-7\]
With that done, we'll move on do dividing 12 by 6, wich is 2.
\[8^{2}+9(2)-7\]
we'll move on to multiplying 9 times 2, wich is 18.
\[8^{2}+18-7\]
Now let's square that 8, remember that when yousee that little "2" up there means that it's multiplying by itself.
So 8 times 8 is 64
\[64+18-7\]
The only thing that's left now is doing some sums and substracctions.
we'll wnd up having:
\[82-7\]
Wich is equal to 75.
Being 75 the answer to the problem.
