Answer: Option b
[tex]x^4= y[/tex]
Step-by-step explanation:
Linear equations have the following form:
[tex]a_1x^n + a_2y^m + a_3w^s + a_4v^h = b[/tex]
Where the exponents n, m, s and h are always 0 or 1
To know which equations are nonlinear, identify among the options given, those that have exponents other than 1 or 0
Note that in option b) the exponent of the variable x is [tex]n = 4[/tex] therefore the equation is nonlinear
Finally the answer is the option b
