x=y4 /2
y4
Assuming the domain and range are suitably defined, then yes. If not, then no.
The expression "4y" represents four times the variable ( y ), while "y4" typically denotes the variable ( y ) raised to the power of 4, or ( y^4 ). In essence, "4y" is a linear expression, whereas "y4" (or ( y^4 )) is a polynomial expression. Their meanings and uses in mathematical contexts are therefore quite different.
You cannot solve it since only one side of an equation is given. If the equation was y4 + 5y2 - 84 = 0 then y4 + 12y2 - 7y2 - 84 = 0 or y2*(y2 + 12) - 7*(y2 + 12) = 0 or (y2 - 7)*(y2 + 12) = 0 then y2 = 7 or y2 = - 12 y = +or- sqrt(7) and, if you are in the complex domain, also y = +or- i*sqrt(12) where i is the imaginary square root of -1.
