Question

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

Answer 1

given radicals

convert them into simplest radical form

a) √49

√49 = \sqrt{7\times 7}

= 7

b) ∛40

∛40 =
`\sqrt[3]{2* 2* 2* 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.
