simple bramble
#

36+27 = 63

#

"the digits of the number gets reversed"

#

personally, I'd just trial and error

idle ore
#

x = tens digit
y = units
so x + y = 9
and 10x + y + 27 = 10y + x

#

27 = 9y - 9x

#

smth like this ig

#

3 = y - x

#

now y = 3+x

#

put this is in first eqn

#

x + 3 + x =9

#

2x=6

#

x=3

#

and then y + 3 = 9

#

so

#

y = 6

#

so number becomes

#

3*

#

36*

#

btw 10x + y makes up the number you know 10s digit and units digit so thats why 10x + y

#

incase u wonder why

#

ok so

#

the close

#

thing

#

how does it work

#

well

#

¯_(ツ)_/¯

#

who cares

abstract forge
#

3?

#

hmm

#

we find p(alpha)

#

and multiply it with (alpha) ^8

#

we do same with beta

#

to get (alpha)^10

#

so we get eq and subtact

#

and rearrange

#

subtracting the eq with alpha and beta we get
a10 - 6.a9 - 2.a8 = 0

#

a10 - 2.a8 = 6.a9

#

for finding :- (a10-2.a8)/2.a9 = 6.a9/2.a9 = 3

#

^^

#

this is given just to make the "find the value of" part smaller

#

else they wouldve made the question way longer
"find the value of (α^10-β^10) ....etc
