How many kilobytes are in in 1 terabyte if a terabyte is 2^40 and kilobyte is 2^10

There are kilobytes in a Terabyte

Step-by-step explanation:

If one Terabyte is bytes and one kilobyte is bytes, then, by simple quotient we can find how many kilobytes are in one Terabyte:

Notice that in the numerator we have 40 factors of "2", while in the denominator we have 10 factors of "2". So we can cancel just 10 common in denominator and numerator and end up with 30 factors of "2" left in the numerator.

On can also use the "properties of exponents" to simplify exponents with the same base.

146%

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
