Question about Casio FX-115ES Scientific Calculator

Common logs (logs in base 10) use the 10^x function : to solve your concern follow the steps below.

enter 4726 Press [SHIFT] [Log] and press = sign to get the answer.

4726 seems to already be on base 10

it's 4*10^3 + 7*10^2 + 2*10^1 + 6*10^0

Decimal is base 10 and binary is base 2.

The columns from right to left in base 10 are:

10^10 10^9 10^8 10^7 10^6 10^5 10^4 10^3 10^2 10^1 10^0

Similarly, the columns from right to left in base 2 are:

2^10 2^9 2^8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0

This site does a good job of explaining the conversion from decimal to binary.

For example, take the number 157. The biggest column that goes into 157 is 128, which is the 2^7th column, so we put 1 in that column. Subtracting 128 from157, we get 29. We start all over again. The biggest binary number going into 29 is 16, which is the 2^4th column. When you subtract 16 from 29, you get 13. We start all over again. The biggest binary number going into 13 is 8. Subtracting 8 from 13, we get 5. Biggest number going in is 4, 2^2th column. 1 left over to go into the 2^0 column.

Pulling it all together, we get:

10011101.

Checking, 128 + 16 + 8 + 4 + 1 = 157.

Good luck.

Let me know if you have any questions.

Calculators work to base '10' not base '12', so you'll have to convert. the S.I. unit of measurement is used for calculators which is metres and they are base '10'. The metre was calculated by a french bloke who got the calculation wrong, but they still use it. Feet and inches are better.

Rephrase the question please. It makes no sense, in particular what are all those TIMES for?

Combine all the logs using the rule log_2(a)+log_2(b)=log_2(a*b)

You get

log_2((x-10)(x-3)/x)=2=log_2(4)

Thus

(x-10)*(x-3)/x=4

Convert it to a quadratic equation (x^2-17x+30=0). the solutions are x=2 and x=15. That should not be too difficult to factor out 5*2=30 -15-2=-17.

Dinary? Never heard that one before. What is a dinary number? Anyway your calculator cannot perform the operations. The Casios can work in Binary (base 2), Octal (base 8), Decimal (base 10) and Hexadecimal (base 16). Some Sharps can do calculations in base 5 (pental).

I am sorry to say but the calculator does not handle Base-N calculations. It only has three calculation types :General (basic) COMPutations, Standard deviation calculation, and regressions.

Letters can be converted into decimal number using ASCII table. Every Character has it own equivalent number. Once converted into decimal (base 10), I could be easily converted into binary (base 2)

You could also use applications or web based applications such as ASCII to binary converter to help you convert it.

Press MODE 4 to switch to the BASE-N mode. Enter the base-10 number and press =. Press SHIFT [BIN] (the LOG key) to switch to base-2 and see the result.

In general, once in the BASE-N mode, to convert a number from one base to another, switch the calculator into the first base using the keys in the third row, enter the number, press =, then switch the calculator into the second base.

Press MODE 1 (or 2) to exit the BASE-N mode.

for converting 486 to the base 10 to base 6 dived 486 by 6 and note the quotients and remainder.

486/6 = quotient = 81 remainder = 0.now divide quotient by 6 and note quotient and remainder.

81/6 = quotient 13 remainder= 3

13/6 = quotient 2 remainder = 1 .

2/6 = quotient 0 remainder= 2.

Hence reading remainder from below we get 2130.

So 486 tot he base 10 is equivalent to 2130 to the base 6.

Thank you.

Press MODE 4 to enter the BASE-N mode. If the display doesn't say Dec, press SHIFT DEC (the x^2 key) to set base 10. Enter the number to convert. Press SHIFT BIN (the log key) to switch to base 2.

Each time you switch the base the current value is redisplayed in that new base.
