There are a couple of worksheets on exponentials and logarithms.
You should know that 5^3 = 125 and so cube root of 125 = 5. How do you find what power is needed to make 2 to the power n=512. Well this is where logarithms come in.
log base2 of 512 = 9 say ” log base two of 512 is 9”. This is equivalent to saying 29 = 512 or that the ninth root of 512=2.
