So in this equation a=4 and b=3, but i don’t know if i should square the number before multiplying it

So we are given the equation:

Then let's plug in 4 for all of the a's and 3 for all of the b's:

And then we solve using PEMDAS:

Then if we divide both the numerator and the denominator by 35, we get:

And thus is the most simplified answer.
