You have 5 choices for the 1st digit of the number. 4 choices for the 2nd digit and 3 choices for the 3rd and final digit. This means that there are 5 x 4 x 3 = 60 3-digit numbers that can be made from 5 different digits subject to each digit only being used once.
Oh, dude, an 18-digit number is called... wait for it... an 18-digit number! Like, it's literally just a number with 18 digits. So, if you ever need to describe a number with 18 digits, you can impress your friends by calling it an 18-digit number. Mind-blowing, right?
no even exponent of a real number can ever result in a negative number. If x is a complex number with the real and imaginary part having the same magnitude, then taking that to the fourth power will result in a real number, which is negative.Example: (2 + 2i)4, or (-2 + 2i)4, or (2 - 2i)4, or (-2 - 2i)4, Just take (2 - 2i)4, as one to see how it works. First take (2 - 2i)2, then we'll square that result.(2 - 2i)2 = 4 - 4i - 4i + 4i2 , but i2 is -1, so we have -8i, then square that is 64i2 which is -64.
The smallest one is 1,008. The largest one is 9,990. In all, there are 500 of them, all of them even numbers divisible by 9. (To find them all, multiply 18 by all integers from 56 to 555.)

No.
yes
No it would be 2-3 digets depending on the number.
There is no last digit of pi. It is possible to calculate the digits of pi an infinite number of times. The one millionth number is 5.
No. I have never known of a text message that meets the 10 digit criteria to ever come back. It merely means that you have sent a text to a phone number. Try texting your home phone number - it will work too. They can disable text messaging, their 'inbox' can be full, etc.
Yes, but only if it is an integer multiple of 100.
no one knows and no one ever will
I know what it is, but Im not telling you guies, ever.
There is a first phone number for ever country

A decimal is a rational number if it ever ends, or if it repeats the same single digit or set of digits forever.
