Question

Divide 12 x 4 √15 by 8 x 3 √3

Answer 1

Hi ,

We know that ,
____________________

Sqrt ( ab ) = sqrt a × sqrt b
____________________


i )sqrt ( 15 ) = sqrt ( 3 × 5 )

= sqrt 3 × sqrt 5 -----( 1 )


According to the problem given,

( 12 × 4 sqrt ( 15 ) / [ 8 × 3 sqrt (3) ]

= [ 48 ×sqrt 3 × sqrt 5 ) ] / [ 24 × sqrt ( 3 ) ]

After cancellation ,

= 2 × sqrt 5

I hope this helps you.
