Depends where you put the brackets !

4 square root of 28 - 2 square root of 2/3=

4 * (square root of [28 - 2] ) * square root of (2/3) =
16.653328
or

(4 *( square root of 28)) - (2 * square root of (2/3)) =
19.5330173
or

4* {square root of [28] - [2*(square root of [2])] } / 3 =
3.28410066
or

4* {square root of [28 - (2*[square root of [2/3]])] } =
20.5395255
or

4 * { (square root of [28 - 2]) * (square root of [2/3]) } =

33.306656

etc

I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

28

square root (28)+1 = 6

Factors

1, 28/1=28

2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)

3, 28/3=9.33333 - not a factor - doesn't go in evenly

4, 28/4 =7

5, 28/5=5.6 - not a factor - doesn't go in evenly

6, 28/6=4.66666 - not a factor

So now we can list our factors - 1, 28, 2, 14, 4, 7

Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Paul

Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

You can use the square-root function for any number, whether it's a perfect square or not. For example, to calculate the square root of 2, press SHIFT [square-root] 2 EXE .

[square-root] is on the x^2 key, just to the right of the ALPHA key.

Two ways:

2ND [square-root] ( 8 7 . 3 4 / 5 ) ENTER

8 7 . 3 4 / 5 ENTER then 2ND [square-root] 2ND ANS ENTER

The first sequence takes the square root of 87.34/5, the second sequence calculates 87.34/5 then takes the square root of the result.

2ND [square-root] ( 8 7 . 3 4 / 5 ) ENTER

8 7 . 3 4 / 5 ENTER then 2ND [square-root] 2ND ANS ENTER

The first sequence takes the square root of 87.34/5, the second sequence calculates 87.34/5 then takes the square root of the result.

Hello,

The square root has a dedicated key sequence [2nd][V square root symbol]

Square root of 21.2846 is entered [2nd][V square root] 21.2846 [ENTER] .

The result is`4.614.

I suspect you want to calculate the 4th root of 21.2846. If it is the case you enter that as

21.2846 [^](1/4) =2.148

Square root can be also entered as [^](1/2)

Cube root is entered as [^] (1/3)

..

nth root is entered as [^](1/n)

Hope it helps.
