Question

If sq. rt. of 2=1.414, sq. rt. of 5=2.236 and sq. rt. of 3=1.732, find the value of (1) sq. rt. of 72 + sq. rt. of 48 (2) sq. rt. of 125 by 64

Answer 1

HELLO......FRIEND!!

THE ANSWER IS HERE,

$1) \: \sqrt{72} + \sqrt{48}$

$= > \: 6 \sqrt{2} + 4 \sqrt{3}$

$= > \: 6(1.414) + 4(1.732)$

=> 8.484+6.928

=>15.412


$2) \: \sqrt{ \frac{125}{64} }$

$= > \: \sqrt{ \frac{ {5}^{3} }{ {8}^{2} } }$

$= > \: \frac{5 \sqrt{5} }{8}$

=> 11.18/8

=> 1.3975

:-)Hope it helps u.

Answer 2

Hi Friend !!!

==================

1) √72+√48

=6√2+4√3

= 6(1.414) + 4(1.732)

= 8.484 + 6.928

= 15.412

2)
$\sqrt{ \frac{125}{64} } = \sqrt{ \frac{ {5}^{3} }{ {8}^{2} } } \\ \\ = \frac{5 \sqrt{5} }{8}$
= 11.18/8

= 1.3975
