Show that sum, difference, product and quotient of two rational numbers are still rational, that is, for any x, y ∈ Q, show that x + y, x − y, xy, x y are rational numbers. (2) Show that √ p is irrational for any prime number p. (3) Use (1) and (2) to show that √ 2 + √ 3 is irrational.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Sorry i meant b in the other question
