Please help me with this answer having a hard time
Ipatiy [6.2K]

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

In this problem we have double parentheses. Which one should we solve first? The answer to that is always the inner most ones:

13[ 6² ÷ (5² - 4²) + 9]

5² - 4²

^^^Here you will have to first take the square of both values

25 - 16

9

13[ 6² ÷ (9) + 9]

Now for the exponents

13[ 6² ÷ (9) + 9]

6²

36

13[ 36 ÷ 9 + 9]

Now for the division:

13[ 36 ÷ 9 + 9]

36 ÷ 9

4

13[ 4 + 9]

Now for the addition

13[ 4 + 9]

4 + 9

13

13[13]

Now for multiplication

169

Hope this helped!
