#

Don't know how to do this

small venture
#

so say root 396 = root(36)root(11)

#

= 6root11

#

do the root 44 now

jagged zenith
jagged zenith
#

then what

small venture
#

okay so now simplify the fraction and combine

#

with the 22/root11

jagged zenith
small venture
#

you got 220/2root11

#

that equals 110/root11

jagged zenith
#

multiple by the donimantor

jagged zenith
#

i see

small venture
#

yep

small venture
#

but just multiply the fraction

#

so fraction * root11/root11

jagged zenith
#

so so far we got 6root 11 22over 11 and 110root11

small venture
#

22 over root 11 right?

jagged zenith
#

by the answer

small venture
#

show me ur working out so far

jagged zenith
#

wait a sec

small venture
#

alright

jagged zenith
#

there

#

handwriting aint the best

small venture
#

its fine i understand it

#

yes so all steps are great so far

#

now join 22 /root 11 - 110/ root 11 together

#

its just like normal fractions

jagged zenith
#

alr

#

-82/root11

#

@small venture

small venture
#

right idea just wrong subtraction

jagged zenith
small venture
#

22 - 110 = -88

jagged zenith
#

๐Ÿ˜ญ

#

mb

small venture
#

its alright u just need practice

#

everything is good so far though

#

the surd denominatior gets into ur head so u forget the easy stuff its alright

#

๐Ÿ˜ญ

jagged zenith
#

yh

#

-88 voer root11

small venture
#

yep

#

okay so do yk what u do now

jagged zenith
#

nope

#

nvr did this type of question

small venture
#

ah its alright

jagged zenith
#

my teacher js gave it to me

small venture
#

so we wanna get rid of that denominator

#

so we multiply the fraction by root11/root11 cuz its the same as multiplying by 1

#

so in reality it doesn't really change anything in the fraction

small venture
#

-88root 11 over 11

jagged zenith
#

?

small venture
#

u multiply both top and bottom

#

of the fraction

jagged zenith
small venture
#

yep nice

jagged zenith
#

now what abt the 6root 11

small venture
#

nothing

#

try simplifying the fraction and see what happens

jagged zenith
#

so 8root11

#

the 6root11+8root11

small venture
#

don't forget the right sign

#

u had -88

jagged zenith
#

yh

#

-8root11

small venture
#

now its just simple old subtraction

jagged zenith
small venture
#

๐Ÿ˜ญsorry

#

i forgot the sign aswell

jagged zenith
#

6root11 -8root11

small venture
#

yess

jagged zenith
#

-2root11

#

did i mess it upp?

small venture
#

๐Ÿ”ฅ

#

nope its right

jagged zenith
#

nice

#

ty

#

only 4 marks tho

#

๐Ÿ˜”

small venture
#

make sure to get good at these cuz its sooo important

#

and ur gonna use it a lottt

#

grade 7+ skill

small venture
jagged zenith
#

yk when it says aroot11

small venture
#

yes

jagged zenith
#

would they mention a minus in the test or not

#

gcse*

small venture
#

no, but if they say an integer then it can be either a positive or negative whole number

#

also happens when u complete the square

jagged zenith
#

i see

#

ty

small venture
#

don't worry, if ur working out is right then just put the answer like u got it

#

no worries

Ah that's how it works

#

yo @jagged zenith

#

if this is solved then please go ahead and run command /solved

boreal goblet
#

I did that and canโ€™t access it now

slate anvil
#

yeah thats the point ๐Ÿ™

#

!!/solved is essentially a cmd that closes your thread

slate anvil

because if your question is solved your thread no longer needs to stay up
