Answer 3

Sure, let's solve the expression step by step:

Step 1: Evaluate the expressions inside parentheses. (3/5 + 1/4) = (12/20 + 5/20) = 17/20

(7/8 - 1/4) = (7/8 - 2/8) = 5/8

Step 2: Square the term (4/5)² (4/5)² = (4/5) * (4/5) = 16/25

Step 3: Perform the multiplication in the second set of parentheses. (5/8) * (16/25) = (5 * 16) / (8 * 25) = 80 / 200 = 2/5

Step 4: Perform the addition and subtraction in the first set of parentheses. 17/20 + 2/5 = (17 * 5 + 2 * 20) / (20 * 5) = (85 + 40) / 100 = 125 / 100 = 5/4

So, the final answer is 5/4, which is equal to 1 and 1/4.
