In MATLAB, you can extract specific digits from a number by converting it to a string and then indexing into that string. For example, to extract the third digit of a number num
, you can use the following code:
numStr = num2str(num); % Convert the number to a string
digit = numStr(3); % Access the third character
Alternatively, if the number is an integer, you can also use modulus and division operations to isolate specific digits.
Take your pick: It could be 33: the only composite number with repeated digits It could be 71: the only prime number It could be 4: the only square number It could be 106: the only composite number with all different digits.
There are 4 digits. You can pick one of them as the first digit. So you can pick the first number 4 ways. Having picked the first number, the second number you can pick in only 3 ways. Having picked the first number and the second number you can pick the third number in only 2 ways. Having picked the first number and the second number and the third number you can pick the fourth number in only 1 way. So total ways of arranging 1468 would be 4 x 3 x 2 x 1 = 24
I won't tell you the answer, but here's a hint, you can use each number more than one time...
Yes and here is one. pick a number between 1-10 times it by nine add the to digits together. the final answer is NINE
from 1-9 have 9 numbers so that we have 9*9*9*9*9=59049 Consider the case of 5-digit number combinations, where each is some digit from 1 through 9. There are 9 different digits you can pick for the first number. Assuming you can have repeats, there are 9 you can pick for the second, 9 you can pick for the third, and 9 you can pick for the fourth and 9 you can pick for the fifth.
A Western Union reference number typically consists of 10 digits. This number is unique for each transaction and is used to track the money transfer. It's important to keep this number secure, as it is required to pick up the funds.
Pick any number at random from 1 to 58. Then pick another, and another etc. When you have six numbers stop. You now have a combination of 6 numbers. There are 40,475,358 such 6-tuples.
Pick a number.
120. There are 6 digits. If we pick the digits in order, there are 6 possible digits for the first digit 5 remaining digits for the second digit 4 remaining digits for the third digit. 6*5*4 = 120.
It can be if you are referring to a certain person as a "pick-up". Or a pick up as a type of vehicle. Pick up is also a phrasal verb.
