Question about Sharp EL-531VB Calculator

I am trying to follow an example in our book and use my EL-531W to solve it. My problem is I am getting different numbers than the book is.

Equation:

e = exponential

10 4 = 10 to the fourth power

8.2 x 10 4 MBa = Noe-(0.693/8days)(4days)

8.2 x 10 4 MBa = Noe(0.7071)

How do I enter e-(0.693/8days)(4days) into the calculator to get e(0.7071)?

No one in class can get the correct anser on this calculator, but we can on other scientific calculators, so I'm pretty sure we are entering it incorrectly into the Sharp.

Thanks!

Hello,

Here is how you enter it.

[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071

some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).

In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.

You can try

0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.

for this I like to use logarithms to solve for N

reason 4 this is logarithms are the reverse of a exponential

log's have specific rules that exp's don't have to follow hence it makes it easier to solve for answers

using the formula*log*b(*mn*) = *n* · *log*b(*m*) will allow you to solve for N then just reverse the answer (do that in your head!!) and whhoollaaa! its an exponential !!!! neetooo

heres the log rules I was telling you about ! they apply to all log's uses

using the formula

heres the log rules I was telling you about ! they apply to all log's uses

1) Multiplication inside the log can be turned into addition outside the log, and vice versa.

2) Division inside the log can be turned into subtraction outside the log, and vice versa.

3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa.

I think it is case of mistaken identity. There is a function called the power function. The general form of it is a*(b)^x or a times (b) to the power of x. a is just a constant factor (not equal to 0) and b is the so-called base ( also different from zero). Personnally I call this function the power function, but you find it is often called the **exponential function.**

The exponential function**e^x **is similar to the power function. The main difference is that its base is a certain irrational number called e (=2.718281828...).

What you want to do, as far as I can guess is to calculate 2000*(1+0.12)^20.

Simplify your life and set 1+0.12 as 1.12, and type in 2000 [*]1.12^20=

1.12^20=9.646293093. Multiplied by 2000, this gives you a final result 19 292.58

**To enter the the power use the key marked as [X^y], [Y^x] or [^]**

No solution, but I have the exact same problem with a Sharp EL-531W calculator. Doesn't matter whether mode is degrees, radians, etc., and resetting with button in back has no effect.

Hello,

Frankly, I do not understand what you want.

I will try to guess.

Calculate the exponential of 135

Use the [2ndF][LN] key to access the exponential e^x

[2ndF][e^x] 135 [=] result is 4.263389948 x 10^(58)

or 4.263389948E 58

Represent 135 in scientific notation

135 =1.35 x10^2 or 1.35 E2

Represent 135 in Engineering Notation

135=135E0

If none of the above answers your question, maybe you should state clearly what you want, I am no seer.

Hope it helps.

EL-531W SHARP:

If you want to find 5 to the power of 6 (5^6)

you hit the 5 button, then the button that says yx ( the x is in the exponent spot) then the 6 so it will looks like this 5^6 then press enter to get the answer...hope that helps!

Hello,

You have several number display formats : Normal1, Normal2, Sci, ENG

If a number is too small or too large and the calculator cannot display it with the necessary number of digits (to satisfy your of decimal digits) the calculator uses Scientific notation

7.4E-14 =7.4x10^(-14)

If you were to use the norma1 or normal2 format you will have

.0000000000000074 but your calculator displays only the first 10 places

You should learn to use and interpret results in scientific format.

Hope it helps

for the mean, just add them together and divide answer by the amount of figures you put in.
as for the others, i'm not sure a standard scientific calculator will do that

You can calculate =4^1.2 in Excel and get
5.278031643

And also in Excel you can determine what the square root of 2 is (2.506628274631) and then in Excel = 5 ^ 2.506628274631 = 56.5012395907155.

I know this is late but maybe it will help later. Assuming I am doing it right. Thanks!

The y^x button is right next to the x^2 button. It is labled with an x raised to a square box (which I will write as x^box). Thus, if you enter (for example)

2 x^box 5 = 32

2 x^box 5 = 32

If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.
