In case of a polynomial in one variable, the highest power of the variable is called the degree of the polynomial. In case of polynomials in more than one variable, the sum of the powers of the variables in each term is taken up and the highest sum obtained is called the degree of the polynomial. Find the polynomial with degree 6. (a) 6x4+7x2 (b) 8x4y2+7x5y3−35 (c) 8x2y2z2+7x2y3z+3x4 (d) 8x6y6+y2+7x3
