same as the ones before, as marissalovescats showed you

anonymous · Answer

@marissalovescats  Im confused with these though.

anonymous · Answer

Expand it out, 

$$4^4 / 4^4 = [4*4*4*4] / [4*4*4*4] $$

Can you go from there?

anonymous · Answer

no...

anonymous · Answer

Well, you can cancel numbers that are common in the numerator and denominator. Does that ring a bell?

jdoe0001 · Answer

is exactly the same, different values

anonymous · Answer

Is anyone going to give me the answer or show me how to do it???

anonymous · Answer

Its 1.

anonymous · Answer

But why?

anonymous · Answer

[4 X 4 X 4 X 4] / [ 4 X 4 X 4 X 4]

Divide both numerator and denominator by 4, 

Now we lose a 4 on both, so it looks like,

[4 X 4 X 4] / [4 X 4 X 4]

Repeat 2 more times and you end up with, 

[4] / [4]

= 1
