simple one but i can't get the answer :(((

mossy canyon
#

if?

granite knot
#

i suppose it asks us to simplify the expression @mossy canyon

shell isle
#

yeah

granite knot
#

except i cant understand the expression

#

is that 712 * sqrt(6)?

shell isle
#

yep

granite knot
#

not smth like 7 + 2 * sqrt(6)?

shell isle
#

712√6

granite knot
#

weird

shell isle
#

oh

#

wait lemme recheck

#

wait no u're right lmao

#

7+2√6

granite knot
#

hmm

shell isle
granite knot
#

trying to

#

also, like

shell isle
#

oh

granite knot
#

$x = \sqrt{\sqrt{6} + 6 + (\sqrt{7 + 2\sqrt{6}})} - \sqrt{6}$, right?

grim coveBOT
#

John Math

granite knot
#

wait

#

yeah, like this?

shell isle
#

yeah yeah

granite knot
#

are you sure? please double check

shell isle
#

lmao ok brb

#

yeah

#

thats correct

granite knot
#

right so

stiff egret
#

I like your handwriting

shell isle
#

thats not even mine 💀💀

granite knot
#

if im correct, the answer should be 1

shell isle
#

thats my friend's

shell isle
#

procedurs

#

the steps

granite knot
#

there are methods that can be used to simplify the expression

#

so

shell isle
#

whats the easisty

#

easiest

#

can the bot show it for me

granite knot
#

observe

shell isle
#

observing

granite knot
#

we have this expression here

#

$x = \sqrt{\sqrt{6} + 6 + (\sqrt{7 + 2\sqrt{6}})} - \sqrt{6}$

grim coveBOT
#

John Math

granite knot
#

we can simplify the

#

$\sqrt{7 + 2\sqrt{6}}$ part

grim coveBOT
#

John Math

shell isle
#

okay

granite knot
#

we know that 7 = 6 + 1

shell isle
#

yeah

granite knot
#

so it can be rewritten as

#

$\sqrt{6 + 2\sqrt{6} + 1}$

grim coveBOT
#

John Math

granite knot
#

noticed anything?

shell isle
#

yeah

#

break down 6 to √6

#

and take out the commons

#

and what.

granite knot
#

$\sqrt{\sqrt{6}^2 + 2\cdot 1\cdot\sqrt{6} + 1^2}$

grim coveBOT
#

John Math

shell isle
#

yeah

#

oh wait

granite knot
#

we notice that it is equal to $(\sqrt{6}+1)^2$

grim coveBOT
#

John Math

shell isle
#

OHHH

#

yeah yesh

granite knot
#

so we get

#

$\sqrt{(\sqrt{6}+1)^2}$

grim coveBOT
#

John Math

granite knot
#

which is obviously just $\sqrt{6} + 1$

grim coveBOT
#

John Math

granite knot
#

now back to our expression

shell isle
#

yeah

granite knot
#

$x = \sqrt{\sqrt{6} + 6 + (\sqrt{7 + 2\sqrt{6}})} - \sqrt{6}$

grim coveBOT
#

John Math

granite knot
#

we went from this to this

#

$x = \sqrt{\sqrt{6} + 6 + (\sqrt{6} + 1)} - \sqrt{6}$

grim coveBOT
#

John Math

granite knot
#

so far so good?

shell isle
#

yeah

#

mhm

granite knot
#

so now lets group terms and see what we can do here

#

$x = \sqrt{6 + 2\sqrt{6} + 1} - \sqrt{6}$

grim coveBOT
#

John Math

granite knot
#

familiar, isnt it?

shell isle
#

yeah

#

looks like uh

#

yeah

#

the one we did earlier

shell isle
granite knot
#

so we get

#

$x = \sqrt{6} + 1 - \sqrt{6}$

grim coveBOT
#

John Math

granite knot
#

and square roots cancel out

shell isle
#

damn

granite knot
#

we're left with x = 1

shell isle
#

thank you so much
