nothing

OpenStudy (mertsj):

does it help you to know that 6^3=216 and 6^4=1296 and 6^5=7776?

OpenStudy (mertsj):

Do you know that the log is the exponent?

OpenStudy (mertsj):

What is the base in this problem?

OpenStudy (mertsj):

6^3=216 6^4=1296 6^5=7776 What is the base?

OpenStudy (mertsj):

In this expression: 6^3=216 the base is 6 and the exponent is 3

OpenStudy (mertsj):

No. The base is 6 because that's the way we define expressions with exponents: 10^4: the base is 10, the exponent is 4 5^7: the base is 5, the exponent is 7

OpenStudy (mertsj):

So in your problem, by definition, the base is 6 and the exponent varies, depending on which ordered pair you select. But clearly the y values are exponents. In other words, the y values are logs beause lobs are exponents.

OpenStudy (mertsj):

So we can say y = log because the y values are exponents

OpenStudy (mertsj):

And as we have discussed, the base is 6 So: y=log_6(x)
