Which of these are partitions of the set of real numbers? a. the negative real numbers, {0}, the positive real numbers b. the set of irrational numbers, the set of rational numbers c. the set of intervals [k, k + 1], k = −2,−1,0, 1, d. the set of intervals (k, k + 1), k = −2,−1,0, 1,

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!
