Question

Math hw for me pls help

Answer 1

13. -75

14. 65536

15. 2

16. 28

17. 6.5

18. 153

Explanation:

13. 2x(-2)+3^2 x 2x(-2^2)+3^0

-4 - 9 x 2 x 2^2 + 1

-4 - 9 x 2^3 +1

-4 - 9 x 8 + 1

-4 - 72 +1

-75

14. 4 x 4^2 x (-2 x 4^2)^2

2^2 x 2^4 x (2 x 4^2)^2

2^2 x 2^4 x (2 x 2^4)^2

2^2 x 2^4 x (2^5)^2

2^2 x 2^4 x 2^10

2^16 = 65536

15. 18 x (-3^3) / 9 x (-3) - 2^4

18 x 3^3 / 9x 3 - 2^4

2 x 3^3 / 3 - 2^4

2 x 3^2 - 2^4

2 x 9 - 16

18 - 16

2

16. -2^-2 / -2^1 x -2^3/ -2^2 + 12 x (-3^5) / 4 x (-3^3)

2^-2 / 2^1 x 2^3/ 2^2 + 12 x 3^5 / 4 x 3^3

2^-2 / 2^1 x 2 + 12 x 3^5 / 4 x 3^3

1 / 2 x 2 + 12 x 3^5 / 4 x 3^3

1 / 2 x 2 + 3 x 3^5 / 3^3

1 / 2 x 2 + 3 x 3^2

1 + 3 x 3^2

1 + 3^3

1 + 27

28

17. -2^4 + -2^2 / -2^3 +(-2^4) x (-2^-2)

-2^4 -2^2 / -2^3 +(-2^4) x (-2^-2)

-2^4 -2^2 / -2^3 + 2^4 x 2^-2

-2^4 -2^2 / -2^3 +2^2

-2^2 x (2^2 + 1) / -2^3 +2^2

-2^2 x (2^2 + 1) / -2^3 + 4

4 + 1 / 2 + 4

5 / 2 + 4

13 / 2 = 6.5

18. (12 x 2^-1 / 4 x 2^-3)^2 - (-3^2)

(12 x 2^-1 / 4 x 2^-3)^2 + 3^2

(3 x 2^-1 / 2^-3)^2 + 3^2

(3 x 2^2)^2 + 3^2

(3 x 4)^2 + 9

12^2 + 9

144 + 9

153
