what's an orkut????????

it is becaoz while conc. on black+ the image of pink dot falls on black spot and is not seen. green dot appear due to combination of colours we see for long time and our rods and cones tire.

mine is simple

1399+1993=(9+4)⁹⁹+(18+1)⁹³

using binomial theorem ultimately u get

=(9⁹⁹+⁹⁹c₁ x9⁹⁸x4+-- -- - - ⁹⁹c₈x9)+⁹⁹C₉₉ X4⁹⁹+(18⁹³+⁹³C¹X18⁹²+- - - )+93X9+1

HERE WHOLE EXPRESSION IS DIVISIBLE BY 81 EXCEPT

(4⁹⁹+93 X 9+1)

(3+1)⁹⁹+31 X 27+1

HERE ALSO USING BT GIVES

AN EXPRESSION DIVIBLE BY81 EXCEPT

=27 X 31+27X 539+2

=27X570+2

ALL IS DIVISEBLE BY 81 EXCEPT 2

MY HANDS ARE PAINING

is it 0.5

ans=2. what do you say

please wait while i type

what's a brainstorm?????????????

great

what do you mean by-"?"

T 4>T3

¹⁰C₃ X2⁷X3³X x³/8³>¹⁰C₂ X2⁸ X3² x²/8²

x>2

now also T4>T2 as done above

solving we get

x<64/21

2<x<64/21

its too long . however i can type if you ensure a salute.

brilliant of course . i have career point postal test series too. so, bt zindabad

Ans =25 root3+6

We have

Let vertex of parabola be at origin

Then eqn. of parabola

Y²=4ax

(24,50) is a point on it

50 x 50=4a x 24

A=(2500)/(4x24)

Equn is

Y² =(2500)/24 x

Putting y =18 we get x =25root 3

Total lenth=25root 3+6

^[

it is a line from which tangents drawn to two circles are always equal
