Think sq root in prime (1&itself) factors so 20... 2, 2, 5 which as a product is 20.
Sq roots aren't evaluate if they have "twin/identical set" factors in the radicand or under the sq root. So sq root of 20 is 2 times the sq root of 5! Where factors such as 3,3,5,5,7,3 has two sets of twins that when evaluate out will become a product same as any not evaluated out. Thus the answer is 15 times sq root 21. Which should be sq root if 4,725.
Now squares you multiply... Be careful with negative bases though (-4) sq is +16 whereas -4^2 is -16. The grouping symbols make the difference!!! The symbols makes it one base with the negative. The latter is -1 times 4^2 so once exponent evaluated then multiply by -1. Which is mathematics foundation ....order of operations!
How will u divide 1000 one Rs. Coins in ten bag so that u can give any amount between 1-1000 by just giving the bags without changing the no of coins in each bag

I figured out how to do this, but I'm not letting the cat (or the coins) out of the bag -- LOL!
I'll give you some hints, though:
The solution involves Base Two place values.
For numbers of coins between 1 and 511, it's just simply a strict application of changing the number of coins into the binary system.
For numbers of coins between 512 and 1000, you have to make an adjustment to your method because the bag with the largest number of coins can only contain 489 coins rather than 512.
If it contained 512 coins, you would need a total of 1023 coins, but you only have 1000, so you have to use 489 as your highest place value.
It is noted that for numbers of coins between 489 and 511, there are now two ways to distribute that number of coins.
You can either change the number into binary and use that representation to tell you which bags to hand out.
Or, you can hand out the bag with the 489 coins in it, change the difference between the number and 489 into binary, and then supplement the 489 bag with binary being used for the additional bags needed (if any).
