Why are the answers so weird? Or rather, really normal.

answer to what?

daring cliff
#

why arent the radicals like

opaque sedge
#

the rational expression at the top?

daring cliff
#

one second i forgot the word

#

why cant i switch the radicals out?

#

and have the same answer

#

i thought 3-sqrt(3) would be the same answer on the one with sqrt(3)

#

of course i could do the math individually

#

but this just seems odd

opaque sedge
#

i think what they did was multiplied by the conjugate of the denominator

daring cliff
#

INTERCHANGEABLE was the word ok

opaque sedge
#

wdym by swapping the radicals though

daring cliff
#

and just have the same answer regardless and swap out the radical?

#

i kind of forgot how to answer these questions its been a while yknow

opaque sedge
#

you wouldn't have the same answer, what is in the radical also affects whats outside of it when multiplying by the conjugate

daring cliff
#

oh yeeaaa

#

you multiply by the conjugate

#

negating the denominator sort of

#

and making the numerator change differently

opaque sedge
#

its called rationalizing the denominator

daring cliff
#

english is only my first language

#

how to make it solved?

opaque sedge
#

type ".solved"

daring cliff
#

.solved

Solved

Use .unsolved if this was a mistake.
