Question

Choose the correct simplification of the expression b5 • b4.

b

b9

b20

b−1

Answer 1

Similar example


You add the exponents when multiplying similar bases


\[\large b^3 * b^7 = b^{3+7}\]


\[\large b^3 * b^7 = b^{10}\]


note: this is NOT the answer as it's just an example

Answer 2

Ohh , okay. Thanks. :D

Answer 3

np

Answer 4

dude you're not supposed to add the exponents, you multiply them. Thats why its called "MULTIPLYING POLYNOMIALS" you're supposed to multiply the exponents to get B^20
