Question

What properties and rules will be used to solve this question:  $$(b^5)^4 \cdot b + 3b^{21} + b^2 =?$$

Accepted Answer

Apply these rules for exponents:

$$(x^a)^b = x^{(a \cdot b)}$$

$$x^a \cdot x^b = x^{(a+b)}$$

$$cx^a + dx^a = (c + d)\cdot x^a$$

and then the Order of Operations, or PEMDAS, rule (Remember: “Please Excuse My Dear Aunt Sally”)
