🤔

#

Hold on

#

#

there we go

#

because my teacher always told me that with questions like these it's best to split the fractions

upbeat furnace Jul 21, 2023, 1:40 PM

#

Why do you have x^1/2 outside the bracket

next hazel Jul 21, 2023, 1:41 PM

#

I just simplified x^2/4

upbeat furnace Jul 21, 2023, 1:41 PM

#

But the answer has x

next hazel Jul 21, 2023, 1:42 PM

#

oh yh

#

Idk how they did that

#

do you happen to have an idea?

upbeat furnace Jul 21, 2023, 1:56 PM

#

when they do

#

$(x^{\frac{1}{2}})^2$

clarence

next hazel Jul 21, 2023, 1:58 PM

#

how come?

upbeat furnace Jul 21, 2023, 1:58 PM

#

oh wait

#

i'm sperging

#

it's 1 yeh

upbeat furnace Jul 21, 2023, 1:59 PM

#

next hazel

you just simplified the denominator

#

and forgot to multiply by 2

next hazel Jul 21, 2023, 2:01 PM

#

multiply what by 2

#

the x^1/2

upbeat furnace Jul 21, 2023, 2:01 PM

#

$(x^{\frac{1}{2}})^2$

latent radishBOT Jul 21, 2023, 2:01 PM

#

clarence

upbeat furnace Jul 21, 2023, 2:01 PM

#

so you multiply the power on the inside by the power on the outside

next hazel Jul 21, 2023, 2:01 PM

#

ohhh

upbeat furnace Jul 21, 2023, 2:02 PM

#

and you get 1

next hazel Jul 21, 2023, 2:02 PM

#

but why just that part

#

and not the rest of the equation

upbeat furnace Jul 21, 2023, 2:02 PM

#

(xy)^2 = x^2 y^2

next hazel Jul 21, 2023, 2:03 PM

#

but how come multiplying it by 2 places it outside of the bracket?

upbeat furnace Jul 21, 2023, 2:04 PM

#

next hazel but how come multiplying it by 2 places it outside of the bracket?

wha

#

it's because they've done (x^1/2)^2

#

which is x

#

and the rest is still squared

next hazel Jul 21, 2023, 2:05 PM

#

oh ok

#

that makes sense
