X10 to the power of x is the EXP button, just press this and then the number it is to the power of!

No there IS NO "[EXP]" BUTTON on the Casio FX-300ES Scientific Calculator.
AND the supposed replacement for it "10^x" button is NOT equivilent.
Just try to calculate 4.18844x10^-4 / 2.324423x10^-5 = and see what answer you get, IT WILL NOT BE CORRECT!
This would be correct if the calculator had a proper [EXP] button, which represent inherently x10^x.
4.18844[EXP]-4 / 2.34423[EXP]-5 will give the correct answer, IF this calculator only had that button.
To get the correct answer using this calculator you will have to input it like this:
(4.18844x10^-4)/(2.324423x10^-5) =
This is amazing and outrageous, considering this is supposed to be scientific calculator, you cannot even enter numbers naturally in scientific notation, you have use parenthesis and tricks and double check to make sure they are all there, or you will get the wrong answer.

Im looking for the total combination for this nuber 13 20 31 36 41 45 permutations i think its called


Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

What are rational numbers


Use the words: decimal part, not decimal fractin
Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number
0.345 345 345 ... =345/999=115/333
In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator


3deb58af-3d70-4f55-adc1-35b7c9392031.jpg
Period is 345

7b3e81fc-c59c-455d-a5f2-e4b169925684.jpg
Period is 1
847342a7-5d3b-4604-b706-2ec9853c2dc7.jpg
Period is 09
8f929e6d-512c-41e2-a253-ffa88c0ab74e.jpg
Period is 79
0417fef1-6661-4f31-868f-8202884893ae.jpg

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of
0.d_1d_2...d_n d_1d_2... d_n ...=(d_1d_2...d_n)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.
Once the fraction is found, one should reduce it to its simplest form.

I am horrible at maths need help asap


With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

Why does canon MP258 printer with scanner can't scan japanese yen paper bill amount 10,000. I tried it over 10 times but it stops,. And when i tried US paper bill, it works well. I need some explanation...


When you scan with any scanner it utilised the software with "Optical Character Recognition functions, usually abbreviated to OCR -> OCR is a field of research in pattern recognition, artificial intelligence and computer vision." to scan and record the scanned object, sometimes it does not or cannot recognise certain symbols or characters because of man made software & hardware have its limitations too.

Hope it helps.
