Answer 2

$\huge \tt \purple{Question}$

Find the cube root of - 343.

Step-by-step explanation:

$\tt \underline\purple{Solution \: ↓}$

$- 343 = ( - 1) \times 343$

$= ( - 1 \times ( - 1) \times ( - 1) \times 7 \times 7 \times 7$

$= ( - 1) {}^{3} \times (7) {}^{3} = ( - 1 \times 7 ) {}^{3} = ( - 7 ){}^{3}$

$\sqrt[3]{ - 343} = \sqrt[3]{( - 7) {}^{3} } = - 7$

So,$\sqrt[3]{ - 343 } = - 7$
