simplify the expression

OpenStudy (anonymous):

OpenStudy (anonymous):

A) 216^2t-1 B) 6^2t-1 C) 6^2t-2 D) 18^2t-2

OpenStudy (anonymous):

add the exponents, that is all

OpenStudy (mathstudent55):

When you multiply powers with the same base, add the exponents.

OpenStudy (mathstudent55):

\(\large a^m \cdot a^n \cdot a^p = a^{m + n + p} \)

OpenStudy (anonymous):

so the answer is C? @mathstudent55

OpenStudy (misty1212):

HI!!\[1+t-2+t\]

OpenStudy (misty1212):

so no, not C for a change

OpenStudy (anonymous):

actually A @misty1212

OpenStudy (anonymous):

@misty1212

OpenStudy (misty1212):

oh no, keep the base the same ! i.e leave it as 6

OpenStudy (anonymous):

but aren't we gonna multiply 6*6*6

OpenStudy (misty1212):

no

OpenStudy (mathstudent55):

Remember that 6 alone is really 6^1

OpenStudy (misty1212):

for example \(2^3\times 2^2=2\times 2\times 2\times 2\times 2\times 2=2^5\)

OpenStudy (misty1212):

the base does not change, just add up the exponents, keep the base

OpenStudy (anonymous):

oh

OpenStudy (mathstudent55):

\(\large 6 \cdot 6^{t - 2} \cdot 6^t=\) \(\large =6^1 \cdot 6^{t - 2} \cdot 6^t\) Now add the exponents, 1 + t - 2 + t

OpenStudy (misty1212):

base how low can you go? https://www.youtube.com/watch?v=l_Jeyif7bB4
