So by #2, that equals log base 5 ^1 - log base 5 ^250 Then by #1, log base 5^1 - (log base 5^125) - (log base 5^2) The middle term equals 3 and the first term equals 0.
10m(n-8) is completely factored. That means there's nothing left in the parentheses to factor out.
m(10n-80) is not completely factored because you can still factor 10 out of the terms in the parentheses. 10(mn - 8m) isn't completely factored because you can still factor m out of the terms in the parentheses.

log base 4 ^ 8
i have no idea what the steps are
its log subscript 4 with a big 8
So what you do is use the change of base formula:
So the answer is ln 8/ln 4, which you can do using a calculator.
they said the answer is -3-log base 5 ^ 2 but idk how to get that
So by #2, that equals log base 5 ^1 - log base 5 ^250
Then by #1, log base 5^1 - (log base 5^125) - (log base 5^2)
The middle term equals 3 and the first term equals 0.
logs are the hardest thing ive had to learn this semester
my teacher said to set it equal to y
you bring the exponent to the denominator to get rid of the negative so you have 1/2^3
then simplify the denominator
1/2x2x2 which is 1/8
It should be 10m(n-8)
10m(n-8) is completely factored. That means there's nothing left in the parentheses to factor out.
m(10n-80) is not completely factored because you can still factor 10 out of the terms in the parentheses. 10(mn - 8m) isn't completely factored because you can still factor m out of the terms in the parentheses.
That's my interpretation anyway.
