The Degree<span>
(for a polynomial with one variable, like </span>
x<span>
) is the largest exponent of that variable.Let's check each terms :
</span>

<span> has degree of 4 (x is an exponent of 1, y has 2, z is an exponent of 1. So 1+2+1 = 4).
</span>

has a degree of 5 (z has an exponent of 5).

has degree 6 ( y has 2 and z has 4. So 2+4=6).
<span>
Now that we have checked each terms, we know that
t</span><span>
he largest degree is 6, so the polynomial has a degree of 6.</span><span>
In short, your answer be 6.
Hope this helps !
