Of the above list of equations a) c) and f) are said to be linear, but I thought linear equations were not allowed to have fractional exponents? Both a) and f) have the square root of a variable (x_3 and x_2 respectively) no?

Hey kingsolomonsgrave.

I agree with you in that if the terms are to a non-unit power (i.e. not x^1) then they are not linear.

If its just the coeffecient that is irrational though then this is OK.
