Question about Casio fx-300ES Calculator

Hello,

Between the x`squared key and the log key there is a key with an x with a raised small figure of a solid square. That is the key you use to enter arbitrary exponents.

- If calculator is in MathIO ( a Math indicator appears on the upper band of the screen), enter the base of the power (here 2). A number 2 with a raised empty square appears.The cursor will blink in the raised square. Enter there the exponent (here 12) and press [=]. Result 4096 appears at the bottom of the screen.
- If in LineIO (no Math indicator appears on the narrow band at the top of the screen), press 2 and then the key I talked about above. On the screen a number 2 appears with a hat and a left parenthesis. Type in the exponent (here 12) , the right parenthesis and press [=]. The calculator should display 4096.000...

Use the rules for exponents and you will calculate it by hand

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in** 6.02* [EE] 23**. When you use the EE key, the base (10) should not appear.

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

1 2 ^ 2 5 2 =

The ^ key is above and left of the 7 key. This is the key you use for raising a number to a power. If you don't get the correct answer, it's because 12^252 is outside the range of the calculator.

Hello! There isn't power to ECM pins 109 and 111 because the ECM relay is not pulling...Pins 1 and 3 (White/Black wire) are tied together in the harness and should not show a change in symptom if jumped together...Also, Pins 1 and 3 are fed battery from fuse # 36 (15A hot at all times) and both pins must read +12 volts...Pin 2 of the relay coil is the pulling ground from the ECM...Reading across pins 1 and 2 with the key in the ON position should not read +12 volts...If it does the relay coil is open...With the key on the relay would show a voltage drop across the coil...Check pins 1 and 3...must be tied together and have +12 volts from fuse # 36 (15A hot at all times)...Replace ECM relay...See photo...............Guru....Saailer...

You use the power root function key accessible with the key sequence [SHIFT][X ^]. I am inserting a screen capture from the manual to show you the sequence.

On the third line of the capture (power root) is the key you must press. In the small rectangle to the left of the radical sign you enter the order of the root: 2 for square root, 3 for cube root, 4 for 4th root and son on.

To calculate the decimal log you use the [LOG] key as shown on capture. For natural log (ln), use the [LN] key. The argument (2/3) in your example should be enclosed inside the parentheses.

The LOG and LN keys do what you have done.

To get 9 to the 16th power, enter 9, "y to the power x" (under the OFF key) then 16, then =

3 to the 12th power is the same, enter 3, y to the power x, 12, =, result 531,441

The inverse key sequence: value 1, 2nd, y to the power x, value 2, returns the xth root of y, e.g. 531,441, 2nd, y to the power x, 12, =, gives you 3 back
