Question

Rewrite each of the following radicals as a rational number or in simplest radical form. a. √49b. ∛40c. √242

Answer 1

Answer

given radicals

convert them into simplest radical form

a) √49

  √49 = \sqrt{7\times 7}

           = 7

b)  ∛40

      ∛40 = $\sqrt[3]{2\times 2\times 2\times 5}$

              = 2 ∛5

c) √242

   √49 = \sqrt{2\times 11\times 11}

           = 11 √2

hence the number are converted into simplest radicals or rational form.
