Answer 1

e) 39^4/13^4 = (39/13)^4 = 3 ^ 4 = 81

f) 25 ^ 7 * 4 ^ 7 = (25 * 4) ^ 7 = 100 ^ 7

g) (1/5)^4 * 100 ^ 4 = (1/5^4) * 100 ^ 4 = 100 ^ 4 / 5 ^ 4 = 20 ^ 4

h) 19^2 / 38^2 = (19/38) ^ 2 = (1/2) ^ 2 = 1/4

i) (0.4 * 5) ^ 4 = 2 ^ 4 = 16

j) (0.125 * 8) ^ 5 = 1 ^ 5 = 1

k) (0.2 * 5) ^ 6 = 1 ^ 6 = 1

l) (1/4) ^ 3 = 1/64

m) (0.02 / 0.01) ^ 7 = 2 ^ 7 = 128

n) (10 ^ 9 * 0.3 ^ 9)  / 3 ^ 9 = (3/3) ^ 9 = 1

o) -4 ^ 5 / 12 ^ 5 = -1/(3 ^ 5)

p) (65/15) ^ 3 = (13/3) ^ 3 = 13 ^ 3 / 27
