Question

Change log to ln, i really don’t understand this…

Answer 1

19.
`log__(8) 64 = 2` ; 20. ln 22020 = 10

Explanation:

I think the question asks to change to log OR ln.

For problem number (19) log will work best.

For problem number (20) ln will work best.

19).

8² = 64 is in the form

`base^(exponent) = number`

we need to write it using log form

`log__(base) number =`what exponent we raise the base to so will give us the number

`log__(8) 64 = 2`

20)

`e^(10) = 22020\\`

`log__(e) 22020 = 10\\`,

but log base e is ln so

ln 22020 = 10

Answer 2

`~~~~~~8^2 = 64\implies \boxed{\log_8 64 = 2}\\\\\\~~~~~~~e^(10) =22026\implies \boxed{\ln 22026 = 10}`
