Q 2 .
A = lim (1.5n + [(1 + 1 /10000)10000 ]n)1/n

=lim ( 1.5n + [(1 + 1 + 10000*9999/2*10-8 + )]n)1/n

=lim ( 1.5n + [(1 + 1 + .49 + .16 + .04 + .008 )])n]1/n

= lim ( 1.5n + 2n)1/n

= lim 2( 1 + (1.5/2)n)1/n = 2 :)

shit !! 1.5 is taken by me as 1 x 5 .. i thought u unnecessarily added 1 before 5 !!

Mani Pal Singh ·

in the2nd 1 the 2nd term is becoming 2 (using binomial)

so
((1.5)n+2n)1/n (ur question needs to be edired)

(3/4n+2n)1/n

(3/4)(1+(8/3)n)1/n

so the answer is

2

Q 2 .
A = lim ( 5n + [(1 + 1 /10000)10000 ]n)1/n

=lim ( 5n + [(1 + 1 + 10000*9999/2*10-8 + )]n)1/n

=lim ( 5n + [(1 + 1 + .49 + .16 + .04 + .008 )])n]1/n

= lim ( 5n + 2n)1/n

= lim 5( 1 + (2/5)n)1/n = 5

// see post 21 & 19

A = lim 5[1 + ((e-100. 100100)/(5 . 100!))m]1/m

ln A = ln 5 + 1/m ln[1 + ((e-100. 100100)/(5 . 100!))m]

ln A = ln 5 + 1/m ln[1 + ((e-100. 100100)/(5 . 100!))m] * ((e-100. 100100)/(5 . 100!))m / ((e-100. 100100)/(5 . 100!))m

ln ( 1 + x )/x = 1 .. . limit application

ln A = ln 5 + 1/m((e-100. 100100)/(5 . 100!))m

take lim ...1/m → 0 ...
so A = 5 .. Q1 .
