Simplify : 5*x^1/3=35

Calculate and simplifie: 2,8*10^-6 m^3*3,5*10^2mm / 4,9*10^4cm^2

Whole calculations please not only answer. Thnx guys you are great.

2. Hi,

Only tips... IMHO, it's unuseful to give answers...

Know that $(a^b)^c = a^{bc}$

This should help you to get rid of the 1/3 power

For the simplification, just simplify by 5 in both sides.
