x^3+4a+5a^2x^6 ascending order

To arrange the expression x^3 + 4a + 5a^2x^6 in ascending order, we need to organize the terms based on the degree of the variable x.

First, let's identify the terms with the variable x. We have x^3 and 5a^2x^6.

Now, let's determine the degrees of these terms. The term x^3 has a degree of 3, while the term 5a^2x^6 has a degree of 6.

To arrange the terms in ascending order, we will start with the lowest degree and proceed to the highest degree.

The term x^3 has the lowest degree, so it will be written first.

The next term is 5a^2x^6, which has a higher degree. Therefore, it will be written after x^3.

Putting the terms together in ascending order, we get:
x^3 + 5a^2x^6 + 4a

So, the expression x^3 + 4a + 5a^2x^6 in ascending order is x^3 + 5a^2x^6 + 4a.
