What is the process for doing the square root of a number? Like how do you do it? not on a calculator.?

Question

like for order of operations you do PEMDAS what do you do to do the square root/ how do you do it
also this is 8th grade math so please don't exlain something I don't do yet

if I could would I being asking you people I have to do it for hw and I don't want to get in trouble for not doing it plus I didn't understand the first time he explained it why would I the secound
?

Answer 1

I hope this is what your looking for. Tha square root of 5 is 25. The square root of a number is that number multiplied by itself.
3=9
4=16
10=100
9=81

Answer 2

Kat,

Without the use of a calculator, (or higher mathematics), you have to use empirical methods, (trial and error) to determine the square root of a number.

Let's take unluckiest number, which is 13 for our example.
Find the perfect squares which are higher and lower than 13.

9 and 16, right?

So, we know the square root of 13 lies between 3 and 4,
since 3 * 3 = 9 and 4 * 4 = 16.

Let's try 3.5 squared.
3.5 * 3.5 = 12.25 - Too low.
3.7 * 3.7 = 13.69 - Too high.
3.6 * 3.6 = 12.96 - Really, really close....

You keep repeating this process until you're close enough to the answer you seek.

------------------------
EDIT: I've re-read your question and I may have misinterpreted what you said. I believe you're asking where a square root fits into the order of operations. Good question.

A square root is really an exponent, (only it's raised to the 1/2 power). I won't go into detail here, but just remember to solve square roots in the same order as you would exponents.

I guess the "new" order of operations should be relabeled -
PERMDAS.

Parenthesis
Exponents
Roots
Multiplication
Division
Addition
Subtraction

You're welcome to e-mail me if you have any math questions. I'm always glad to help, (as time permits).

I hope I've answered your question.

Answer 3

you got to find 2 numbers that one which has a perfect square root such square root of 25 is 5 and so on. So if you square root of 50 the 2 numbers would be square root of 25 and square root of 2 square root of 25 is 5 so there is no square root of so the result is 5 square root of 2 and that is who u solve all square root problems. Some are more trickier than others. But procedure is the same

Answer 4

the square root property

u(2)(squared)=d the u= the square root of d (like the symbol of the square root over d)
if u (2)(squared)=d,then u= (plus or minus the square root of d) (the symbol of square root over d)

not sure if that is what you were looking fo but ex.
u (2) (squared) = 36
put the square root symbol over both side which takes away the (2) which means you have u left over, then the square root of 36 is 6 so u = 6 but it is also -6 ( since it is plus and minus)and that is your answer.

Answer 5

OMG this is 8th grade math?????

k, sorry. anyways, you know your squares, or how my math teacher said to do it: let's say you have like, the square root of seventeen. Seventeen is not a square, so:
the square root of 16 is eight.
the square root of twenty-five is five.

so the square root is somewhere between four and five.

Answer 6

ANNOOYYINNNG!!! I hate this but you gotta guess and check hun!!!! Start with a number you think is pretty close!! (based on what u no from ur basic math like 7 *7 ) and then keep going up squaring or down. :) GOOD LUCK

Without alot of algebra you cant do it. This is alot easier.

Answer 7

you multiply the number being rooted by that same number

Answer 8

wow, i remember doing this in my algebra 2 class in high school. 8th grade? you're smart!

i vaguely remember you need to perform something called interpolation. it's been years. try to look it up. hope that leads you in the right direction.

Answer 9

Ask your teacher
