Question

49×7rootx=(343)root1/3​

Answer 1

Step-by-step explanation:

$\star\underline{\underline{\bold{Answer :}}}$

$\hookrightarrow \: 49 \times 7 \sqrt{x} = 343 \sqrt{ \frac{1}{3} } \\ \hookrightarrow7 \sqrt{x} = 7 \sqrt{ \frac{1}{3} } \\ \hookrightarrow \sqrt{x} = \sqrt{ \frac{1}{3} } \\ \\ \Longrightarrow by \: squaring \: both \: side \: we \: get - - > \\ \\ \hookrightarrow \: x = \frac{1}{3}$
