hi all,
i think i solved the geometry problems correctly, and 'my coorect answers' contain cubeth roots..... now, the prob is that i cant enter this value as answer even when i enter the decimal value...... can someone please suggest something on this..... or is there something that i need to know.....

You have to enter the EXACT value of the root. Manage to do it.

the cube root of a would be a^(1/3)

aight! ... thanks.
