$\log(9)=\log_{10}(9)=\dfrac{\log_{5}(9)}{\log_{5}(10)}$

In my opinion, that is the simplest form. However, your teacher may want you to remove powers and factors of 5. In that case, the result is ...

$=\dfrac{\log_{5}(3^{2})}{\log_{5}(5\cdot 2)}=\dfrac{2\log_{5}(3)}{1+\log_{5}(2)}$

What is 25/100 in simplest form

barxatty [35]

It would be 1/4. because 25 divided by 5 is 5. 100 divided by 5 is 20.
5 can be divide again so it would be 1 and 20 can be divided by 5 so it would be 4. Put them together and it would be 1/4.

- Find the value of x. Round to the nearest tenth of a unit.

Alik [6]

$x = 34.2$

$\sin(20) = \frac{x}{100} \\ 0.3 = \frac{x}{100 } \\x = 100 \times 0.3 = 34.2$
