Question

Choose the correct simplification of the expression b5 ⋅ b4

Answer 1

Answer:

$b^5 \cdot b^4=b^9$

Step-by-step explanation:

the correct simplification of the expression $b^5 \cdot b^4$

To multiply the exponents we use exponential property

$a^m \cdot a^n = a^{m+n}$

when the base are same and the exponents are in multiplication then we add the exponents.

$b^5 \cdot b^4=b^{5+4}$

We add the exponents 4+5 becomes 9

$b^5 \cdot b^4=b^9$

Answer 2

20 * b(squared) would be the simplification of b5 * b4
You are just multiplying the two number together. You just have to remember that b4 is  just b * 4...  So b * 4 * b * 5 would equal 20 * b squared
