Question

by what number should bracket one by two bracket power minus one Be multiplated so that the product may be equal to (minus 4 by 7) power -1​

Answer 1

Answer:

-2/7

Step-by-step explanation:

$(\frac{1}{2}) ^{-1}$$x$$=(\frac{-4}{7} )^{-1}$

We need to find x in the equation.

$x = \frac{(\frac{-4}{7}) ^{-1} }{(\frac{1}{2}) ^{-1} } = (\frac{-4}{7}) ^{-1} (\frac{1}{2} )^{1} = (\frac{-4}{7}$× $\frac{1}{2} )$ $= \frac{-2}{7}$

-2/7
