Answer:
-13a^2 + 170ab - 13b^2.
Step-by-step explanation:
1. 36(a+b)^2 - 49(a-b)^2
This is the difference of 2 squares: a^2 - b^2 = (a + b)(a - b).
36(a+b)^2 - 49(a-b)^2
= (6(a + b) + 7(a - b))( 6(a + b) - 7(a - b))
= (6a + 7a + 6b - 7b)( 6a - 7a + 6b + 7b)
= (13a - b)(-a + 13b)
If you require the expansion of this it is:
-13a^2 + 170ab - 13b^2.
We are given expression: 
Let us distribute 3/8 over exponents in parenthesis, we get
We can get x and y out of the radical because, we get whlole number 1 for x and y exponents for the mixed fractions.
So, we could write it as.
Now, we could write inside expression of parenthesis in radical form.
