19.$$log__{8} 64 = 2$$ ; 20. ln 22020 = 10

Step-by-step 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

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