Just multiply the like terms.
Remember that an exponent x an exponent, you will add them up.
OpenStudy (dtan5457):
So evaluate:
\[a \times a^8\]
\[b^8\times b^7\]
OpenStudy (anonymous):
Recall that when you multiply powers with the same base, keep the base the same and add the exponents. Because the order of multiplication doesn't matter, you might rewrite as\[(aa^8)(b^8b^7)\]
OpenStudy (anonymous):
ab⁸ b⁵⁶

Sorry. Can't read your response. All I see is a bunch of question marks inside black diamonds.
OpenStudy (dtan5457):
You multiplied the exponents instead of adding them.
OpenStudy (anonymous):
Anyway, here's an example\[x^2x^5=x^{2+5}=x^7\]
OpenStudy (anonymous):
oh...a8 b15

Actually a x a^8 is really a^1 x a^8. Want to check your answer?
OpenStudy (anonymous):
so its a⁹
OpenStudy (anonymous):
Just remember that if there is no exponent shown, it is assumed to be 1.

Sorry. Can't read your last response. But if you said a^9 b^15, you're right and congratulations!
