Suppose a company needs temporary passwords for the trial of a new payroll software. Each password will have two letters, followed by one digit, followed by one letter. The letter W will not be used. So, there are 25 letters and 10 digits that will be used. Assume that the letters can be repeated. How many passwords can be created using this format?

The answer is 156,250

There are 26 letters in the alphabet but you can not use W leaving 25.

There are 3 digits that will be letters and ten digits.

So the problem will be

= 25x25x10x25 = 156,250

Just tested on this and the answer was right.

Step-by-step explanation:

45

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
