Answer:
Explanation:
To simplify the expression, let's break it down step by step:
1. Simplify the innermost expressions first. The square root of 36 is 6, and five minus one is 4.
So the expression becomes:
3/7 * (1 + 6)^2 - 4^3
2. Next, perform the calculations inside the parentheses and exponent:
(1 + 6)^2 = 7^2 = 49
4^3 = 4 * 4 * 4 = 64
So the expression becomes:
3/7 * 49 - 64
3. Now, perform the multiplication and subtraction:
3/7 * 49 = 21
21 - 64 = -43
Therefore, the simplified expression is -43.
