Express each logarithm in terms of In 2 and In 5.
Sladkaya [172]

Answer:

5ln2-3ln5

2ln5-ln2

Step-by-step explanation:

∵ 32=2^{5}

∵ 125=5^{3}

∵ ln\frac{32}{125}=ln\frac{2^{5}}{5^{3}}

∴ ln2^{5}-ln5^{3}=5ln2-3ln5

∵ 12.5=\frac{125}{10}=\frac{25}{2}=\frac{5^{2}}{2}

∴ ln12.5=ln\frac{5^{2}}{2}

∴ ln5^{2}-ln2=2ln5-ln2

I just need the answer in word form
nadya68 [22]

Answer:

May 7, May 13, May 19

Step-by-step explanation:

Bethany wears jeans every two days. So, if she wears jeans on May 1, then she will wear jeans on May 3, May 5, May 7

Similarly, she wears running shoes every 3 days. So if she wears running shoes on May 1, then she will wear them on May 4 and May 7.

So she will wear both on May 7.

We can see a pattern that she wore both after six days of wearing them together first time.

Using the pattern we can say that she will again wear them both on May 13 and May 19th ..
