Tiana is thinking of a number, which she calls n. She subtracts 5 and then finds half of the difference. Which expression represents Tiana's number? 1 (n-5) c) What is Tiana's final number if her starting number is 23? Tiana's final number is ?​

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!
