x ^ ( - 1 / 7 ) = ( 1 / 2 )
mean
1 / seventh root of ( x ) = 1 / 2
reciprocal value:
seventh root of ( x ) = 2 Raise both sides to the power of 7
[ seventh root of ( x ) ] ^ 7 = 2 ^ 7
x = 2 ^ 7 = 128
x^(-1/7)=(1/2)
Please help
the example given was x^(-1/7)=(1/5) so that solved x=78,125. but i have no idea what to do thanks!
