Hi;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Easy way!!!
You can do a Quick Approximation but its hard to do it Quickly unless you are real good at Multiplication/Division of Large numbers!!
If two or more thoughts intersect, there has to be a point!

Re: Easy way!!!
I got to get the answer as 5.227 * 10^3

Re: Easy way!!!
Hi soha,
That answer is wrong:
5.227 * 10^3 = 5227 the correct answer is 522.7. Have you copied the problem right?

Have a look at Post #5 above.
Try to Approximate the Numerator and Denominator to the nearest 
possible multiples of 5 or 10 and then you can simplify quickly!
I'll give you a few examples.....................

Re: Easy way!!!
Hi soha;
Then there is problem, 5.227 * 10^3 is 5227 the answer to your first problem is 522.7. I have checked it 3 times by computer.

Re: Easy way!!!
yes , the answer is
The power of 10 should be 2 instead of 3. Plz check the Question again... Did you copy it EXACTLY??

Re: Easy way!!!
Yes, it cannot be 3. It is off by a factor of 10. There is no possibility of error. Maybe a typo in the book.

Try This Approach..............
Give more expressions where you are facing a problem currently or otherwise....
