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
