Answer:

11. 10 x [(29 + 7) ÷ (5² – 2⁴)] = 70

12. [(9 + 3²) x 5 ÷ 30] + 5 x 2 = 13

13. 24 - 5 + [(2⁴ x 3²) + (16 ÷ 4)] = 167

14. 122 - [6⁰ x (4 + 5)] = 122

15. 132 x [(12 + 5) – (5² – 2⁴)] ÷ 2 = 528

Step-by-step explanation:

11. 10 x [(29 + 7) ÷ (5² – 2⁴)]

     = 10 x [29 + 7  ÷ (25 - 16)]

     = 10 x (36 ÷ 9)

     = 10 x 7

     = 70

12. [(9+ 3²) x 5 ÷ 30] + 5 x 2

    = [(9 + 9) x 5 ÷ 30] + 5 x 2

    = [(18 x 5) ÷ 30] + 5 x 2

    = (90 ÷ 30) + 5 x 2

    = 3 + 10

    = 13

13. 24 - 5 + [(2⁴ x 3²) + (16 ÷ 4)]

    = 24 - 5 + [(16 x 9) + (16 ÷ 4)]

    = 24 - 5 + (144 + 4)

    = 19 + 148

    = 167

14. 122 - [6⁰ x (4 + 5)]

    = 122 - (6⁰ x 20)

    = 122 - 0

    = 122     Note: Any number multiply by 0, the number is always be 0.

15. 132 x [(12 + 5) – (5² – 2⁴)] ÷ 2

    = 132 x [(12 + 5) - (25 - 16)] ÷ 2

    = 132 x (17 - 9) ÷ 2

    = 132 x 8 ÷ 2

    = 1056 ÷ 2

    = 528

Additional Knowledge:

GEMDAS is the rule that can be used to simplify or evaluate complicated numerical expressions with more than one binary operation.

Important Note:

In a particular simplification, if you have both multiplication and division, do the operations one by one in the order from left to right.

That's All, Thank You!
