Given x>0 and y>0, select the expression that is equivalent to 3rd root of 216x^12y^13 1) 72x^4y^13/3
2) 6x^4y^13/3
3) 6x^1/4y^3/13
4) 72x^1/4y^3/13

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
