I understand how to do it but am having trouble with the mathematical aspect. I have redone the problem quite a few times but keep getting stuck. Could you help?

**Math, Precalc**

6*(9^(1/x))-13*(6^(1/x))+6*(4^(1/x))=0

**Physics**

A block (weight= 10kg) is sitting on a surface with friction (coefficient= 0.5). A force (push) is applied to the end of the block, 35 degrees below the horizontal. Calculate the magnitude of the force to move the block.
