Question

Find (3/7)⁴– x ×(7/3)-³=3/7 ​

Answer 1

Step-by-step explanation:

$( \frac{3}{7} ) ^{4} - x \times ( \frac{7}{3}) ^{ - 3} = \frac{3}{7}$

$\frac{81}{2401}-x\times \left(\frac{7}{3}\right)^{-3}=\frac{3}{7}$

$\frac{81}{2401}-x\times \left(\frac{27}{343}\right)=\frac{3}{7}$

$\frac{81}{2401}-\frac{27}{343}x=\frac{3}{7}$

$-\frac{27}{343}x=\frac{3}{7}-\frac{81}{2401}$

$-\frac{27}{343}x=\frac{948}{2401}$

$x=\frac{948}{2401}\left(-\frac{343}{27}\right)$

$x=-\frac{316}{63}$

$x = \frac{27}{343}$

$x = \frac{3}{7}$
