Question

$if \: \sqrt[3]{125} \times \sqrt[3]{27} = 3 \times x \: then \: x is$
​

Answer 1

$\sqrt[3]{125} = 5 \\ \sqrt[3]{27} = 3 \\ given \: \sqrt[3]{125} \times \sqrt[3]{27} = 3x \\ 5 \times 3 = 3x \\ 15 = 3x \\ x = \frac{15}{3} \\ x = 5$

Answer 2

$\sqrt[3]{125} = 5$

$\sqrt[3]{27} = 3$

5 × 3 = 15. eqn 1

5 × 3 = 3 × x. . (Given) .eqn 2

from eqn 1 and 2

15 = 3 × x

x = 5
