plug y back in and you should get answer 10.The answer should be 2 point something. (since 3 ^2= 9,If you get more than 3 or less than 2,......
3^y=10

Take the log of each side:
Log(base 10) 3^y = Log (base 10) 10 = 1
log (base 10) 3^y = y log (base 10) 3
log (base 10) 3 = 0.477
0.477y = 1
y = 1/0.477 = 2.0964

-
log(3^y)=log(10)
by property
y * log(3) = log(10)
divide
(ignore the parenthesis)(image sake) log(10)
(ignore the parenthesis) y= ----------------------------------------…
(ignore the parenthesis)(image sake) log(3)
there you go. Don't have log on my phone so i don't answer it, but his is pretty much it.
plug y back in and you should get answer 10.
The answer should be 2 point something. (since 3 ^2= 9, but 3^3=27)
If you get more than 3 or less than 2, something is wrong
