Question

Hi, can you explain why x^-1/2 = 1/2√x?
Thanks.

Answer 1

\[x^{\frac{1}{2}}=\sqrt{x}\] it is just exponential notation

Answer 2

the minus sign means take the reciprocal, so
\[x^{-\frac{1}{2}}=\frac{1}{\sqrt{x}}\]

Answer 3

there is no two in it though, so maybe the question was about something else

Answer 4

Oops I meant why

\[\frac{ 1 }{ 2 }x ^{-\frac{ 1 }{ 2 }} = \frac{ 1 }{ 2\sqrt{x}}\]

Answer 5

same reason

Answer 6

Thank you :))

Answer 7

yw

Answer 8

let me guess, derivative?

Answer 9

Yes!
