Answer 1

Answer:

The number to be multiplied is - $\frac{81}{7}$.

Step-by-step explanation:

Let x be the number.

Given that on multiplying x to $(\frac{-1}{7} )^{3}$ we get $(\frac{-3}{7} )^{4}$

This can be represented as follows

$(\frac{-1}{7} )^{3}$ * x=$(\frac{-3}{7} )^{4}$

⇒$\frac{-1}{7^{3} }$ * x=$(\frac{-3}{7} )^{4}$

⇒-x = $\frac{(-3)^{4} }{7^{4} }$ * 7³

⇒ - x= $\frac{81}{7}$    

⇒ x= - $\frac{81}{7}$.
