Question

7+3{-1+5[2-(-9-7)4]+2

Answer 1

1000

Step-by-step explanation: 7+3{-1+5[2-(-9-7)4]+2} can be simplified as follows:

First, we need to solve the innermost parentheses first: -9-7 = -16

So, 7+3{-1+5[2-(-16)4]+2} becomes 7+3{-1+5[2+64]+2}

Next, we need to solve the brackets: 2+64 = 66

So, 7+3{-1+5[66]+2} becomes 7+3{-1+330+2}

Now, we need to solve the innermost parentheses again: -1+330 = 329

So, 7+3{329+2} becomes 7+3*331

Finally, we need to multiply: 3*331 = 993

So, the final answer is 7+993 = 1000.

Therefore, the value of the given expression is 1000.
