Answer 2

To simplify the given expression, let's break it down into steps:

Step 1: Convert mixed numbers to improper fractions. 6 4/5 = (5 * 6 + 4) / 5 = 34/5 5 3/4 = (4 * 5 + 3) / 4 = 23/4

Step 2: Subtract the fractions. 34/5 - 23/4 = (34 * 4 - 23 * 5) / (5 * 4) = (136 - 115) / 20 = 21/20

Step 3: Square the fraction 4/7. (4/7)² = (4²) / (7²) = 16/49

Step 4: Multiply the result from Step 2 by the squared fraction from Step 3. (21/20) * (16/49) = (21 * 16) / (20 * 49) = 336/980 = 84/245

Therefore, the simplified value of the expression (6 4/5 - 5 3/4) * (4/7)² is 84/245.
