Question about Casio FX-115ES Scientific Calculator

U look eofr teh button on the caluclater thats says squrae root or has its sign and if it above teh button press second and shift then the botton

If it has no name , it is probably a cheap one without many features. Most basic calculators have digit keys to enter numbers, and some operation keys to specify operations to be performed on the numbers entered.

Operation keys are +(add), -(subtract), X (multiply) , and / (divide). You may have an equal sign to display the result.

You may also have a square root key.

That is about all.

For an operation +,-,x, or / you enter the first number, then the operation key, then the second number and the = key. The result will be displayed.

For a square root , enter a positive number then press the square root key.

Good luck.

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.

Just complete the square

x^2-22x-10=x^2-2(x)*11+11^2-11^2-10=(x-11)^2-121-10=(x-11)^2- 131.

Use the identity a^2-b^2=(a-b)(a+b) with a=(x-11) and b= square root (131)

Solutions are**x1= 11 + square root (131) **and **x2=11-square root (131)**.

By the way, the calculator you are refer to cannot perform symbolic algebra calculations.

x^2-22x-10=x^2-2(x)*11+11^2-11^2-10=(x-11)^2-121-10=(x-11)^2- 131.

To calculate the square root of 9, press

2nd [square-root] 9 ) =

The square-root is the shifted function of the x-squared key, just to the left of the 7 key. The close-parenthesis is needed to balance the open-parenthesis automatically inserted by the square-root function.

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.
