    y=x^10

    If I bring the power of 10 across to Y, instead of isplaying Y to the 10th root, how else can it be shown?

    is it 1/y^10?

    I'm not quite sure what you're trying to achieve?

    y^(1/10)( cos(pi/10) + i sin(pi/10) ) should make sense.

    1 / y^10 is incorrect.

    If he's transposing for X then is it:

    x = y^(1/10)

    My brain feels like mush tonight; apologies if I'm off.

    You're right of course, but he appears to be asking if there's a way other than that.

    x = y^(1/10)

    That makes sense. I can't believe how bad my Maths has become:eek:
    I got a higher level B in the leaving cert 8 years ago:eek:

    1/y^10 can also be written y^(-10), I guess that's where you got mixed up
