Question

simplify: (100/49)^(-1/2)

Answer 1

Google it...

Answer 2

For removing negative sign, just switch denominator and numerator..

Like:

\[\large (\frac{x}{y})^{-a} \implies \color{blue}{(\frac{y}{x})^{a}}\]

Answer 3

So what will it become by removing negative sign:

\[\huge (\frac{100}{49})^{\frac{-1}{2}} = ??\]

Answer 4

(100/49)^(-1/2) = 1/(100/49)^(1/2)

Answer 5

\[1/\sqrt{100/49}\] = 1/(10/7)

Answer 6

Then reverse it too..

Answer 7

1/1 x 7/10 = 7/10

Answer 8

Yeah...that's what google said, too... :-)

Answer 9

\[\large (\frac{100}{49})^{\frac{-1}{2}} \implies (\frac{49}{100})^{\frac{1}{2}} \implies \sqrt{\frac{49}{100}} \implies ??\]
