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.
