c)ans:-6

Answer 2

Answer:

Q4

$a) \sqrt{81 } = \sqrt{9 \times 9 } = 9$

$b) - \sqrt{9} = - \sqrt{3 \times 3} = - 3$

$c) \sqrt{ - 36} = \sqrt{ 6 \times - 6} = 6$

Q5

$a) \sqrt[3]{27} = \sqrt[3]{3 \times 3 \times 3} = 3$

$b)\sqrt[3]{64} = \sqrt[3]{4 \times 4 \times 4} = 4$

$\sqrt[3]{ - 216 } = \sqrt[3]{ - 6 \times - 6 \times - 6} = - 6$
