How would you rewrite the expression 30a^3+40a^5 by factoring out the GCF?
To factor out the greatest common factor (GCF), we first identify the common factor that divides both terms. In this case, the common factor is 10a^3.
We can factor out the GCF by dividing each term by 10a^3:
30a^3 + 40a^5 = 10a^3 * 3 + 10a^3 * 4a^2
Then, we can factor out the GCF by writing it outside the parentheses and leaving the remaining terms inside:
30a^3 + 40a^5 = 10a^3(3 + 4a^2)
