Answer 2

Answer:

a) 10/16

b) (-5)/(-8)

c) 40/64

d) 80/128

e) (-80)/(-128)

Step-by-step explanation:

5/8 = x/16

x = (16/8) ^ 5

x= 2^5 = 10

5/8 = y/(-8)

y= {(-8)/8} ^ 5

y= (-1) ^ 5 = (-5)

5/8 = z/64

z= (64/8) ^ 5

z= 8^5 = 40

5/8 = a/128

a= (128/8) ^ 5

a= 16^5 = 80

5/8 = b/(-128)

b= {(-128)/8} ^ 5

b= (-16)^5 = (-80)
