my question is below...
I didn't understand what Arturo O. meant with his answer. could some body explain it in an easier way?
Here's my question again.
(Also, I'm in 7th grade!)
How do I express 10^5 as a power of 3?
Here's how Arturo O.'s answer was.
Set 10^5 equal to 3x and solve for x.
3x = 10^5
log(3x) = log(10^5)
x log3 = 5
x = 5 / log3
Then 3 to the power 5/log3 gives 10^5.
35/log3 = 10^5
