can any1 tell me how to simplify square roots?? PLEZ HELP!!!?

Question

home work help

Answer 1

us a calculator you can find one by googleing for it

Answer 2

start dividing them say the question is the root of 640start with the easy divide it by 10 then keep dividing it every time you have two numbers take that number out and multiply all the double numbers you have, put them out of the brakets and keep the number under it so for this divide by 10 and get
64 and 10
now divid 64 by two and you get 32 2 10
now divide 10 by 2
you have 32 2 5 2 but 32 can still be simplified by dividing by 2
now you have 16 2 2 2 5
now divide 16 by 2
8 2 2 2 2 and 5 then divide 8 by 2
4 2 2 2 2 2 and 5 and once more divide 4 by 2
2 2 2 2 2 2 2 and 5
so now you have 3 sets of 2's which gives you six
so your answers 6 and the square root of 10 see

Answer 3

OK well squares roots are number divided by two of the same numbers like the square root of 144 is 12 because 12 *12=144 or 64 the square root would be 8*8. i hoped this help :p

Answer 4

Understand your factors. Like 9 is a factor of 72, 81, etc. because these numbers are all divisible by 9 and the square root of 9 is 3, which is a simple square root.

Answer 5

you should locate the utmost available ideal sq. that the wide type is divisible through (4, 9, 16, 25 etc.) So for root 20, the utmost divisor will be 4. the subsequent line would seem as if: root 4 X root 5, because 4 higher through 5 is 20. this would simplify to 2root5 because the sq. root of four is two. wish it helped! :)

Answer 6

only way i can explain is by example:
for instance, square root of 88
break it down a lot
square root of 44 x 2
square root of 2 x 2 x 22
square root of 2 x 2 x 2 x 11
can't break down anymore (with whole numbers)
so take two 2's out, which become one 2 on the outside, and you are left with 2 x square root of 22

Answer 7

if the base number can be multiplied by itself its it square root
144 is 12 , 81 is 9, 9 is 3
but that' s just the tip of the iceberg

Answer 8

hun get a calculater and punch the number you want than press the press the sq. root botten

Definition: This describes a "long hand" or manual method of calculating or extracting square roots. Calculation of a square root by hand is a little like long-hand division.

Answer 9

You break it up into it's factors that can be evenly square rooted.
Ex: sqrt (80) = sqrt(4)*sqrt(4)*sqrt(5) = 2*2*sqrt(5), which is 4sqrt(5).

Prime factorization will help you find the square rootable factors.

Answer 10

There is no such thing as simplifying square roots unless you are referring to something in algebra. You must be using the wrong terminology.

Answer 11

1. Find the log, divide that by 2, and then find the anti-log.
2. Calculate by hand. See: http://www.nist.gov/dads/HTML/squareRoot.html
3. Use a calculator.
