Explanation:
this just means to put the given values for the variables into the places of the variables and then simply calculate ...
9.
g⁵ - h³, g = 2, h = 7
2⁵ - 7³ = 32 - 343 = -311
10.
c² + d³, c = 8, d = -3
8² + (-3)³ = 64 - 27 = 37
11.
a²×b⁶, a = 1/2, b = 2
(1/2)² × 2⁶ = 1/4 × 64 = 16
12.
(r - s)³ + r², r = -3, s = -4
(-3 - -4)³ + (-3)² = (-3 + 4)³ + 9 = 1³ + 9 = 10
