Question

Simplify √12 + √192 -√147

Answer 1

Answer:

√12 + √192 -√147

= 2√3 + 8 √3 - 7√3

= 10 √3 - 7 √3

= 3√3

on putting √3 = 1.732

we get

3√3 = 3 × 1.732 = 5.196

$..$

Answer 2

Answer:

$⟹ \sqrt{12} + \sqrt{192} - \sqrt{147}$

$⟹2 \sqrt{3} + 8\sqrt{3} - 7\sqrt{3}$

$⟹ \sqrt{3} (2 + 8 - 7)$

$⟹ \sqrt{3} (10 - 7)$

$⟹ \sqrt{3} (3)$

$⟹ 3\sqrt{3}$

$putting \: the \: value \: of \: \sqrt{3} = 1.732$

$we \: get$

$⟹3 \times 1.732 = 5.196$
