By the given information, we can write the equation as........
(ar^3 - a) = 4(ar^2 - ar)
=> a(r^3 - 1) = 4ar(r - 1)
=> r^3 - 4r^2 + 4r -1 = 0
I suppose, the contant term -1 is missing in the question. Am I right?

1) Convert 3/4 into decimal, we will get 0.75. This equal to .75 Therefore the answers is c.
2) Convert 1/3 into decimal, we will get .3333..... , Therefore .45 > .3333.... Therefore the answer is b.

((1/square root x) - (square root x))^3
Let us take y = ((1/square root x) - (square root x))^3
On simplifying, we will get...
y = x^(-3/2) - 3x^(-1/2) + 3x^(1/2) -x^(3/2)
Differentiate with respect to x, we will get.
dy/dx = (-3/2)x^(-5/2) + (3/2)x^(-3/2) + (3/2)x^(-1/2) - (3/2)x^(1/2)
On simplifying
dy/dx = 3/2(-x^(-5/2) + x^(-3/2) + x^(-1/2) - x^(1/2))
Let me know, if there is any correction in my steps.

ABC is a right-angled triangle, right angled at A and AD is the altitude on
BC. If AB : AC = 3 : 4, what is the ratio of BD to DC?
can anyone help me with this?
What is the difference between sequence and pattern? Can any one help me to get a clear picture?
I need to take a presentation on this tomorrow, so please help its urgent.

Hi !!
I too guessed the same, since i am not sure of the answer, i asked you.
Thanks a lot Ganesh.

Victoria woke up in the middle of the night and looked at her digital clock, it said 2:58, then she saw it change to 2:59 and then 3:00. Bored she began adding up the digit as they changed 15,16.3. Hmmmm
At 3:01 the digit added up to 4. A minute later the sum was 5. Victoria liked the pattern. She turned on the light and began figuring. She found that of all the digit sums on a 12 hour digital clock only one is unique meaning there is only one time that give you that sum.
What is the unique digit sum, and what is it's corresponding time?
I know, you people will come up with a solution.

Hey !!
I got it now. Thanks for your help.
Is the number [(44+\sqrt{1996})^{100}] odd or even?
I am confused while looking at it, help me to approach the problem to get the answer.
