I forgot most of my math from school and uni and now I want to calculate the mesh size of a porous gel.
I came up with this equation:
x^3 = 0.8 (a+x)^3
I measured all values for a using nanoindentation so I need to solve this equation for x.
Could anybody help please?
Thanks a lot
Welcome to the forum.
Cube root both sides
note: cube root of 0.8 is approximately 0.9283.
On a calculator press the y^x button (some calcs show incorrectly as x^y) with (1/3) as the y value.
ie. 0.8 y^x (1/3)
Hope that's what you need.
