Multiply the numerator and denominator by the conjugate of the denominator.

[cobalt spade]

Like this?

[zealous goblet]

What

Do $\frac{9(17+\sqrt{37})}{(17-\sqrt{37})(17+\sqrt{37})}$

[nimble forge]

Ravi (No Lifer)

[subtle jay]

Not sure what happened to the denominator.

[zealous goblet]

Yeah same doubt here

[subtle jay]

Yeah, that would be correct.

[zealous goblet]

@cobalt spade do you get why we did this

[cobalt spade]

Yeah to get rid of the square root on denominator

Get it now

[subtle jay]

Right. And what will the denominator become?

[cobalt spade]

17^2 - 37

[subtle jay]

Yes. Well, it should be easy from here.

[cobalt spade]

Yeah I got it

[zealous goblet]

I’ll leave this to you

[cobalt spade]

Do any of you understand this one?

[subtle jay]

Factor each number, then use properties of powers.

[cobalt spade]

Do any of you know the formula for this one?

[zealous goblet]

There isn’t a formula

Yk how to do long division right?

Search up polynomial long division

[surreal lily]

i've honestly never been a fan of long division, this stuff takes up too much space

[zealous goblet]
