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

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
