Part b please

[vale turtle]

rationalise the denominators

Well if u rationalise the first couple

What dyu get?

[dull eagle]

denom always = -1

so multiply by -1

so rhs = -4

[vale turtle]

no

ur meant to show that

[dull eagle]

lhs =

root1-root2, root 2 - root 3...

keeps going till you end with root1 -root25=-4

[vale turtle]

don't multiply the sides by -1

[dull eagle]

okay so

(1-5)/-1 = 4

so 4=4

[vale turtle]

ye

[dull eagle]

why not?

[vale turtle]

Well don't need the 4=4

[vale turtle]

Well because ur showing that the lhs = rhs

U don't assume they're the same instantly

ur showing that they're the same

[dull eagle]

kk ty

[vale turtle]

Like if u focus on lhs

U only focus on lhs

[dull eagle]
