Let a and b be rational numbers. the difference of a and b is.. (always/sometimes/never rational.) the product of a and b is.. (always/sometimes/never rational.) √ab.. (always/sometimes/never rational.)

Answer with explanation:

Rational Number: Those numbers which can be Represented in the form of where,p and q are any integer ,and q≠0.A rational number when represented in terms of decimals ,is either terminating or non terminating repeating.For example: 0.777....,0.58,0.23.

It is given that , A and B are rational numbers.

1. Difference of A and B is

a.Always Rational

2. Product of A and B is

  a. Always Rational

3.

c. Sometimes Rational

For, example ,A=4,B=9

then ,→→Rational

And, If A=6, B=8

then ,→→Irrational

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

the discriminant is 64 + 4*1*12 = 112

this is prime.
