Question

(√225/729-√25/144)÷√16/81=?

Answer 1

Hi ,

1 ) √225 = √ 15 × 15 = 15

2 ) √729 = √ 27 × 27 = 27


3 ) √25 = √5 × 5 = 5

4 ) √144 = √ 12 × 12 = 12

5 ) √ 16 = √ 4 × 4 = 4

6 ) √ 81 = √ 9 × 9 = 9

Now ,

( √225/√729 - √25/√144 )÷√16/√81

= ( 15/27 - 5/12 ) ÷ 4/9

= [ ( 60 - 45 )/108 ] × ( 9/4 )

= ( 15/108 ) ( 9/4 )

= ( 15 × 9 )/ ( 108 × 4 )

After cancellation ,

= 5/16

I hope this helps you.
