indices

2.5q^-1r

[zenith cape]

Why

And how

[shy warren]

When u divide indices , u subtract

[zenith cape]

Wait the answer says it’s 5r/2q

[shy warren]

Oh Ik

Does is say make a letter the subject?

[zenith cape]

No

[shy warren]

U just cancel out

[zenith cape]

Just sump lift

[shy warren]

Both numbers are divisible by 2

So that leaves u with 5/2

Then

The p’s cancel out

The q’s don’t cancel out but the top one doesn’t have a q

And then the r is there but not in the bottom

Poorly explained

[zenith cape]

Ohhhhh

[shy warren]

10pppqqqqqr
4 pppqqqqqq

[zenith cape]

I get it

[shy warren]

Look at 10/4 as a fraction

It can be simplified

The p’s cancel out, 5 of the qs cancel out and the r is left and then the 10/4 can be simplified to 5/2

[zenith cape]

[stiff tiger]

the quetion was to find x in terms of y

what to do ?

[near harbor]

x+y =10 so x=10-y

[near harbor]

Just means rearrange to make x the subject
