2) -4X + 3 Y = 2

Solve 2^x=32 and rewrite this equation in a logarithmic form

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
