What is the degree of 7x^6?

Example -

4x2 + 6x + 5

This polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5

The exponent of the first term is 2

The exponent of the second term is 1 because 6x = 6x1

The exponent of the third term is 0 because 5 = 5x0

What? 5x0 = 5?

Well, anything with an exponent of 0 is always equal to 1

So, 5x0 = 5 * x 0 = 5 * 1 = 5

Since the highest exponent is 2, the degree of 4x2 + 6x + 5 is 2
