Question

work out: a.√0.49 b.∛343

Answer 1

Answer:

a. 0.7

b. 0.58566

Step-by-step explanation:

as you know that 7^2 =49 so, its square root is 0.7

Answer 2

Answer:

a. √0.49

                = $\sqrt{0.7 * 0.7}$                         {0.49 = 0.7 * 0.7}

                = $\sqrt{0.7^{2} }$

                = 0.7

b. ∛343

           =$\sqrt[3]{7 * 7 * 7}$                               {343 = 7 * 7 * 7}

          = $\sqrt[3]{7^{3} }$

          = 7

Formula:

     $\sqrt[n]{}x^{n}$ = x

n th root of x to the power n is x
