# Introduction to logarithms watch

1. Help meh.

Don't even know where to start :/

2. it is not really logarithm work...

you get the same results with

{ P + Q } / { PQ }

and

{ K2 - 1 } / { K - 1}
3. A denominator can go under each part of a numerator

eg (3 + 2)/ 6 = 3/6 + 2/6

Another hint: remember difference of 2 squares?

When I first attempted it I substituted x and y, but to no avail.

I feel like I'm missing something -_-

splitting fractions.

{ V + W } / VW = V / VW + W / VW

splitting fractions.

{ V + W } / VW = V / VW + W / VW
Thank you

Why could I not see this before
7. 3/(3x6) = 1/6 The 3's cancel because you can create an equivalent fraction by dividing both numerator and denominator by 3.

Has that helped?
