Question

simplify 49^(-1/2)power

Answer 1

well this means simply\[\sqrt{49^{-1}}\]

Answer 2

A 1/2 power is a square root, and a negative power is in the denominator, so 49^(-1/2) is

\[\frac{ 1 }{ \sqrt{49} }\]

Answer 3

in order to remove the - from the equation you must flip 49 \[\sqrt{\frac{ 1 }{ 49 }}\]
which simplifies to
\[\pm \frac{ 1 }{ 7 }\]
