Question

1. If √ 0.09 * 0.9 x = 0.9 * 0.09 * √y find x/y​

Answer 1

Answer:

1/10.

Step-by-step explanation:

√0.09 ˣ0.9 ˣX = 0.9 ˣ 0.09 ˣ√Y

0.3 ˣ 0.9 ˣ X = 0.081 ˣ√Y

0.27 ˣ X = 0.081 ˣ √Y

0.27/0.081 = √Y/X

30/9 = √Y/X

30/√9 = Y/X

30/3 = Y/X

10/1 = Y/X

X/Y = 1/10.

Answer 2

Step-by-step explanation:

0.09= 9/100 and 0.9= 9/10

√9/100*9/10x = 9/10*9/100 √y

√81/1000 = 81/1000 √y

√81=9 and √1000 = 10√10

9/10√10√x = 81/1000√y

√x/√y= 10√10/9*81/1000

√x/√y = 9/10√10

squaring both side

x/y= 81/1000

x/y = 0.081
