Question

the value of .............

Answer 1

40% of 30 = 40x30/100=12
Similarly
10% of 30 = 3

90% of 30=27
$\sqrt{3} + \sqrt{12 } - \sqrt{27}$
1.73+3.46-5.20 =0

Answer 2

[tex]= \sqrt{30 * 10/100} + \sqrt{30*40/100} - \sqrt{30*90/100} \\ = \sqrt{3} + \sqrt{12} - \sqrt{27} \\ = \sqrt{3} + 2 \sqrt{3} - 3\sqrt{3} \\=3 \sqrt{3} - 3\sqrt{3} \\=0[/tex]
