Answer 1

$a)\sqrt{100} = \color{red}10$

$b) \sqrt[4]{256} = \sqrt[4]{4 {}^{4} } = \color{red}4$

$c) \pm \sqrt{25} = \pm \sqrt{5 {}^{2} } = \color{red} \pm5$

$d) - \sqrt{144} = - \sqrt{12 {}^{2} } = \color{red} - 12$

$e) \sqrt[3]{ - 8} = - \sqrt[3]{8 {}^{} } = - \sqrt[3]{2 {}^{ 3} } = \color{red} - 2$

$f)3 \sqrt{16} = 3 \times 4 = \color{red}12$
