Rewrite the expression as an equivalent ratio of logs using the indicated base.log17(52.875) to base 10.

s2008m [1.1K]

Answer:

$log_{17}52.875 = log_{10}52.875 : log_{10}17}$

Step-by-step explanation:

Given

$log_{17}(52.875)$

Required

Convert to base 10

To do this, we make use of the following logarithm laws;

$log_ba = \frac{log_{10}a}{log_{10}b}$

In the given parameters;

$a = 52.875$

$b = 17$

Substitute these values in $log_ba = \frac{log_{10}a}{log_{10}b}$

$log_{17}52.875 = \frac{log_{10}52.875}{log_{10}17}$

Represent as a ratio

$log_{17}52.875 = log_{10}52.875 : log_{10}17}$

Hence;

$log_{17}(52.875)$ is represented as $log_{17}52.875 = log_{10}52.875 : log_{10}17}$

What is the greatest common factor of 96x^2 and 88x

nevsk [136]

Answer:

GCF = 8x

Step-by-step explanation:

Find the GCF of the constants:

96 and 88 are both divisible by 8 which is the GCF of the constants.

The GCF of the variables is x, as you cannot divide x by anything more than x.

The total GCF is 8x.
