Question

degree of polynomial 5x2y4z+6xyz3+23​

Answer 1

the degree is 1 as the highest power is 1

Answer 2

I think your question is $5x^{2}y^{4}z \: + \: 6xyz^{3} \:+\: 23$

If this is right then the degree of the polynomial is 4.

$({}^{.}.{}^{.} \: 4 \: is \: the\: highest \: power \: in \: the\: given \: polynomial)$
