815*537 = 2.56*1039 in standard form Therefore it will have 40 digits.
There are 16 digits in a Mastercard number, usually starting with 5.Mostly, they are just an account number. Some of the digits, however, are "check digits." That is, they come from some mathematical formula being applied to some of the other digits. That makes it near impossible to simply make up a string of 16 digits that are a valid credit card number. Of course, the location of the check digits and the formula which generates them are carefully guarded secrets.So, sorry, no example.
Any prime numbers of about 66 or 67 digits will do.
12 multiplied by 22 is equal to 264. This can be calculated by multiplying the tens digits (1 and 2) to get 2, and then multiplying the ones digits (2 and 2) to get 4. Finally, combine these results to get the answer 264.
I believe the factors/digits would have to be either 1, 1, 2, 3 (12 combinations) or 1, 1, 1, 6 (4 combinations).
Find a four digit number whose digits will be reversed when multiplied by nine?
All of them.
36 is twice the product of its digits multiplied. 3 times 6 equals 18, and 18 times 2 equals 36.
30 multiplied by 15 is equal to 450. This can be calculated by multiplying the two numbers together using the standard multiplication algorithm, which involves multiplying the units digits first, then the tens digits, and adding the results. In this case, 0 multiplied by 5 is 0, and 3 multiplied by 5 is 15. Combining these results gives the final answer of 450.
WRONG.
When multiplying numbers with significant digits, count the total number of significant digits in each number being multiplied. The result should have the same number of significant digits as the number with the fewest significant digits. Round the final answer to that number of significant digits.
The new prime number, 2 multiplied by itself 57,885,161times, less one, has 17,425,170 digits.
Two (or four) digits added together cannot equal 42. Two-digit numbers multiplied together cannot equal 82.
A two digit number whose two digits added together equal 42 and multiplied together equal 82
Probably not. Some of the digits are probably check digits, calculated from the other digits, based on some formula. This means that if any one of the digits changes, another digits - or other digits - have to change, too.
Mostly, they are just an account number. Some of the digits, however, are "check digits." That is, they come from some mathematical formula being appled to some of the other digits. That makes it near impossible to simply make up a string of 16 digits that are a valid credit card number. Of course, the location of the check digits and the formula which generates them are carefully guarded secrets.
