Question

1)√0,16 ⋅ 4
2)√27 * √3
3)√5/√20
4)√0,01⋅ 225⋅144
5)3√(-17)²
6)√9/64

Answer 1

1) ✓0.16*4=0.4*4=1.6
2)✓27*✓3=✓27*3=✓81=9

Answer 2

$\sqrt{0.16} \times 4 = 1.6$
$\sqrt{27} \times \sqrt{3} = \sqrt{27 \times 3} = \sqrt{81} = 9$
$\frac{ \sqrt{5} }{ \sqrt{20} } = \sqrt{ \frac{5}{20} } = \sqrt{ \frac{1}{4} } = \frac{1}{2} = 0.5$
$\sqrt{0.01} \times 255 \times 144 = 0.1 \times 255 \times 144 = 25.5 \times 144 = 3672$
$3 \sqrt{ { - 17}^{2} } = 3 \sqrt{289} = \sqrt{ {3}^{2} \times 289 } = \sqrt{2601} = 51$
$\frac{ \sqrt{9} }{64} = \frac{3}{64}$
