a)
(1/4)⁴ * 20⁴ = (1/4 * 20)⁴ = 5⁴ = 625
b)
15³ * (1/5)³ = (15 * 1/5)³ = 5³ = 125
c)
24² * (1/4)² = (24 * 1/4)² = 6² = 36
d)
(1/3)⁴ * 6⁴ = (1/3 * 6)⁴ = 2⁴ = 16
e)
(8/5)³ * (5/4)³ = (8/5 * 5/4)³ = (2 * 1)³ = 2³ = 8
f)
(36/7)² * (7/9)² = (36/7 * 7/9)² = (4 * 1)² = 4² = 16
g)
35²/7² = (35/7)² = 5² = 25
h)
63²/9² = (63/9)² = 7² = 49
i)
32³/16³ = (32/16)³ = 2³ = 8
j)
6³/18³ = (6/18)³ = (1/3)³ = 1/27
k)
42² : 6² = (42/6)² = 7² = 49
l)
5⁴ : 15⁴ = (5/15)⁴ = (1/3)⁴ = 1/81
