let Log base2 [m]=p
p^2-3p=10,
p2-3p-10=0,
(p^2-5p) (2p-1 )=0,
p(p-5) 2(p-5)=0,
(p-5)(p 2)=0,
p=5 or -2.
But log base 2 [m]=P,
log base2 [m]=5,
log base2 [m]=log base2 [2^5],
m=2^5=32,
or log base 2 [m]=p,
log base2 [m]=log base2 [2^-2],
m=2^-2=1/4
.: m=32 or 1/4
(6)
No of man =5,
No of woman =3,no of
committee =3 total no of
people =5+3=8.
A no of ways of foring the
committee=8C base3,
but nC base r=n!/(n-r)!r!,
8C base3=8!/(8-3)!3!,
=8!/5!3!= 8*7*6*5/5!
*3*2=56ways.
NOTE: ^ MEANS RAISE TO POWER.
BASE MEANS A SUBSCRIPT. Eg
6base2 means that small 2 will be down the 6.
6base2[M] means 6base2
then M.
