Explanation:-
4. Solve:(1) 12√75÷3√3 (2) 3√12×√18
Sol. of (1) 12√75÷3√3 Sol. of (2) 3√12×√18
=12√75÷3√3 =3√12×√18
=12√75/3√3 =3×1√12×√18
=4√25 =3√216
=4×5 =3√2×2×2×3×3×3
=20 ans =3×2×3√2×3
=18√6 Ans.
5. (1) Simplify: √50-√98+√168 (2) Rationalise the denominator 1/√7
Sol. of (1) Simplify: √50-√98+√168 Sol. of (2) Rationalise the
=√50-√98+√168 denominator 1/√7
=5√2-7√2+2√42 =1/√7×√7/√7
=-2√2+2√42 Ans. =1×√7/√7×√7
=√7/7 Ans.
6. Simplify: 8 ∛16 + ∛54 + ∛250
Sol.=8 ∛16 + ∛54 + ∛250
=8×3√2×2×2×2 + 3√2×3×3×3 + 3√2×5×5×5
=8×3×4 + 3×3√2×3 + 3×5√2×5
=8×12 + 9√6 +15√10
=96+9√6 +15√10 Ans.
