Question

By what number should (5/6)-³ be multiplied so that the product is (-2/5)².​

Answer 1

Answer:

Hello mate!

Let the no be x.

$(\frac{5}{6 }) ^{-3} * x = (\frac{-2}{5} )^{2}$

$\frac{216}{125} *x = \frac{4}{25}$

$x=\frac{4}{25}$ ÷ $\frac{216}{125}$

  = $\frac{4}{25}$ × $\frac{125}{216}$

  =  $\frac{500}{5400 }$

x   =  $\frac{5}{54}$.
