Since exponents are hard to type, we usually use the carrot key, "^".

I get the correct answer on my calculator. Could it be set to scientific notation and there is a "-1" off to the right?

Let me know.

Good luck.

Paul

Press 1 E 4

The E means "times 10 to the" so 1E4 is 1*10 to the 4th 10 to the 4th.

use the up caret for exponents

ex: 10 to the 2 is 10^2

ex: 10 to the 2 is 10^2

Use the (-) key for negative numbers (not just exponents) instead of the - key. The - is to subtract one value from another, (-) is to input a negative value.

To enter powers of 10 you use the [EE] key.

EX: 1.07 x10^(38) type in 1.07[EE]38 [=]

EX: 1.07 x10^(38) type in 1.07[EE]38 [=]

I am not sure what you mean. I will try to guess.

If you use the universal power key marked [^] you can use any type of exponent, Just enclose the expression for the exponent in parentheses to avoid ambiguities.

EX: exponential of -3X+5

[2nd][LN] [( ] [(-)] 3 [X,T,Theta] [+] 5 [)]

If by exponents you mean powers the result will be displayed usually as decimals.

I suggest you enter the calculations you have to perform and press [ENTER]. The calculator will inform you in case of ERROR. In case of error with message QUIT or GOTO, select the GOTO option and you will be taken to the offending entry.

Usually you do not use the prefix micro by itself, it must be followed by the name of a unit: 1 micrometer=10^-6 meter. This being said, you want to enter 100*10^-6 and raise it to power 2.

For this you can use the exponent rules.

In what follows, I will enter (10^-6)* 100 and square it. I will use the change sign (-) or [+/-] key

(-6) [2nd][10 to x] [*] 100 [=] [x^2] [=]

The first = calculates 100*10^(-6), the second [=] calculates the square of the number obtained after the first [=].

There are other ways that use parentheses to avoid ambiguities, but I think this is the safest one for you. Be warned that the result will most likely be displayed in scientific format, 1.00 -08 where the -08 will be raised with respect to the main level line. If not, the result will be 0.00000001

For this you can use the exponent rules.

- 100*10^-6=(10^2)*(10^-6)=10^(2-6)=10^-4; product of powers =>algebraic sum pf exponents
- (10^-4)^2=10^(-4*2) =10^(-8) ; power of power =>product of exponents.

In what follows, I will enter (10^-6)* 100 and square it. I will use the change sign (-) or [+/-] key

(-6) [2nd][10 to x] [*] 100 [=] [x^2] [=]

The first = calculates 100*10^(-6), the second [=] calculates the square of the number obtained after the first [=].

Hi,

You have a key labeled [Y to the x], use it for all the powers or roots that do not have a dedicated key or key sequence. Let the key be [^]

Ex: 13.675 to the power 1.33 is entered as 13.675 [^] (1.33) [=].

The result is 32.41778634

Ex: (-64)[^](2/3) [=] gives 16 as result. The (-) is the change sign key

Ex: (2.87655)^(-6.778) is entered as 2.87655 [^] ( (-) 6.778 ) [=] 0.0007758

The (-) is the change sign (or the negative of), not the regular minus. When you have a negative exponent or a complicated exponent, it is safer to enclose the whole exponent inside parentheses.

Hope it helps.

Press MODE and select one of the two complex modes.

Hi Loringh,

see, high exponents are +ve powers, while low exponents are -ve powers.

e.g. for 1200000=1.2X10^6=1.2E+6 (high exponents)

for 0.0000000012=1.2X10^-9=1.2E-9 (low exponents)

I think so easy ?

Thanks
