Question

$a) \sqrt{49 = }$
$b) \: \sqrt{16 = }$
$c) \: \sqrt{400 = }$
$d) \sqrt[3]{8000} =$
$e) \sqrt{64 = }$
$f) \: \sqrt[3]{125 = }$
$g) \sqrt{121 = }$
$h) \sqrt{144 = }$
​

Answer 1

$a) \sqrt{49} = {7}^{2} = 7$

$b) \sqrt{16} = \sqrt{ {4}^{2} } = 4$

$c) \sqrt{400} = \sqrt{ {20}^{2} } = 20$

$d) \sqrt[3]{8000} = \sqrt[3]{ {20}^{3} } = 20$

$e) \sqrt{64} = \sqrt{ {8}^{2} } = 8$

$f) \sqrt[3]{125} = \sqrt[3]{ {5}^{3} } = 5$

$g) \sqrt{121} = \sqrt{ {11}^{2} } = 11$

$h) \sqrt{144} = \sqrt{ {12}^{2} } = 12$
