how would i go about this ? @mathstudent55
OpenStudy (anonymous):
well, when multiplying with the same base.... you would add the exponents
OpenStudy (anonymous):
so it would be x^6+2
OpenStudy (alexandervonhumboldt2):
x^(6+2)
OpenStudy (anonymous):
then simplify

OpenStudy (anonymous):
so x^8 ?
OpenStudy (anonymous):
yup
OpenStudy (mathstudent55):
Same base, add exponents.
OpenStudy (anonymous):
thanks @trindawg @AlexandervonHumboldt2
OpenStudy (mathstudent55):
Correct.

This is why you add the exponents when you multiply two powers with the same base.
I'll use your problem as an example.
power 6 means 6 x's power 2 means 2 x's
\((x^6)(x^2) = ~~~~~~~~~~~~xxxxxx ~~~~~~~~~~~~~~~~~~~\times~~~~~~~~~~~~~~~~~ xx\)
now we have 8 x's
\((x^6)(x^2) =~~~~~~~ xxxxxxxx\)
8 x's mean an exponent of 8
\((x^6)(x^2) = ~~~~~~~~~x^8\)
8 = 6 + 2
\((x^6)(x^2) = x^{6 + 2} = x^8\)
In general:
\(a^m \times a^n = a^{m + n} \)
