Question about Casio FX-115ES Scientific Calculator

10(4705.3)-(45)(1019.2)

______________________

{ [ (10)(285)-(45)exp 2] [(10)(104,051.82)-(1019.2)exp2 ] }exp 1/2

Answer should be .989

User manual does not have examples of this type equation.

Yeah use bracket sign if it in double enclosed use two open parenthesis and close on the other other side. Usually it is max it in triple parenthesis or bracket.

Example

((2x-2)-(2x+4)) { = usually means you gonna use three parenthesis or bracket ((( ))).

[ = means (( ))

( = means single ( ).

Goodluck.

Just use parentheses for all brackets

The key on the fx-155ES is marked "x10^x" and is located just to the right of the decimal point key.

For your first example, press 1 2 7 x10^x 3 + 2 3 7 x 10^x 3 =

For your second example, 1 2 3 x10^x (-) 3 - 2 3 0 x10^x (-) 6 =

The "(-)" key is located just above the "RCL" key.

For your first example, press 1 2 7 x10^x 3 + 2 3 7 x 10^x 3 =

For your second example, 1 2 3 x10^x (-) 3 - 2 3 0 x10^x (-) 6 =

The equivalent of the EE or EXP button on the Casio Fx-115ES is marked
as x10^X. It is located at the bottom right of the key pad left of the =
key.

To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.

Example Enter the mass of the proton m_p in kilograms

**1.6726217 [x10^X] [(-)]27 [=] **

In grams the value above is multiplied by 1000.

or**1.6726217 [x10^X] [(-)]24 [=] **

Since the calculator has the physical constants (the FX-991ES definititely has them)

To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.

Since the calculator has the physical constants (the FX-991ES definititely has them)

- Display the proton mass in kilograms
- [SHIFT ][7] to open the constants catalog,
- type 01 for the proton mass, then press the [x^-1].
- Divide the result by 1000
- You should get 5.978638635 x10^23

If your calculator is SetUp for Math Input/Output (MATHIO), a result that gives a radical will remain in radical form. If a radical appears in a denominator the whole expression is rationalized: Any radical left is put in the numerator. 1/Sqr(3) is displayed as Sqr(3)/3.

Press [MODE][3][2]. In first column enter known x-coordinates (1 and 5), in second known y-coordinates (2 and 6). The solution you are looking for is in form Y=A+B*X where X=3. Your calculator computes A and B after you enter data. To calculate Y (which is equal to A+B*3 press [SHIFT][1][7][1][+][SHIFT][1][7][2][*][3][=]. The result should be 4.

If you're in the MthIO mode, press the fraction key (the solid box over the hollow box on the key just below the CALC key), enter the numerator, press down-arrow, and enter the denominator.

If you're in the LineIO mode, enter the numerator, press the fraction key, and enter the denominator.

If you're in the LineIO mode, enter the numerator, press the fraction key, and enter the denominator.

You have a key that is marked with two rectangles separated by a horizontal bar. This symbolises a fraction.

In MathIO, pressing the key displays the template of a two-level fraction. You are supposed to use the navigation keys to move cursor to the top rectangle to enter the numerator. Then you use the Down Nav key to move cursor to the rectangle in denominator and enter the denominator.

Hello,

You must first eliminate the denominators by reducing the different expressions to the same denominators. Use the distributivity property of multiplication to expand your terms. Gather similar monomials. Do all the cleaning to reduce your equation to one of the 2 types that the calculator can handle.[Mode][5:EQN] [3: ax2+bx+c] or [4:ax3+bx2+cx+d]

**Remember :Any solution that makes one of the original denominators equal 0 must be rejected.**

**Hope it helps.**

Unless I am failing to understand your problem, just combine like terms to get:

9x^2+2x+4 and then enter those coefficients into the quadratic solver.

That will get you the two answers -- both of them will be complex.

If you wanted to turn those two answers into factors (complex) of the original equation simply

change the signs on each and put an x in front.

Of course, the quadratic formula would also work.
