Answer 1

Answer:

log20 base 10

Step-by-step explanation:

log1 can be written as log10 base 10

also log10 base 10 + log 2 base 10 is log 20 base 10

As, log x + log y = log xy

Answer 2

Answer:

the answer is log₁₀20

Step-by-step explanation:

we can write 1 as log₁₀10.

so, now we have equation as

                    log₁₀2+log₁₀10

by applying the identity logₙa+logₙb=logₙab

            log₁₀2+log₁₀10=log₁₀20

hope it helps!!!!
