Welcome to Logarithm

Please show all clear steps please, thank you.

Ex1. Solve for x
a) 2.5^x = 11

Ex2. If log a = x and log b = y, determine the following on terms of x and y.
a) log (third root of ab^2)

b) a + log4b

Ex3. Solve
a) log x base 8 + 2log x base 8 = 2

That would help a lot, thank you so much! ^.^
