maths problem

[true glen]

how would i get started on this i don’t want anyone to just tell me the answer

[waxen star]

Think about what happens if u rationalise each of those fractions

[true glen]

alright i will do that now

[waxen star]

yeah especially the ||denominators||

[true glen]

-1 on the bottom

[waxen star]

exactly

so the numerators flip signs

So what happens to the sum

[true glen]

so -1+root2

[waxen star]

yeah

so now think about what would happen to the other fractions

[true glen]

should i rationalise another

[waxen star]

without actually you know having to rationalise another

[waxen star]

If that helps definitely

[true glen]

ok

[waxen star]

the aim is to try spot a pattern

[true glen]

so the patter is that it’s the second surd minus the first surd

[true glen]

but like how would i use this to find the solution to the entire sim

[waxen star]

Well what's gonna cancel

It goes all the way up to root(100)

[true glen]

some surds can be turned into integers

like root 4 root 9 root 16 ?

wait

hang on

they will all cancel apart from root 100

[true glen]

so will the answer be root100-1

[waxen star]

yeye

[true glen]

yay

[waxen star]

Which is just

[true glen]

9

[waxen star]

W

[true glen]

wow thanks for the help

it seems so easy now

lol

[waxen star]

no worries
