Move the options into the explanation to show whether the sum of a rational number and an irrational number is always rational or
irrational.
Let x =
Assume x is a rational number.
V7+
By subtracting from both sides of the equation, we find V7
Because x and are both rational numbers, x ล is
However, V7=x and V7 is
SOX-
must be an Irrational number
ูู
ู
Since we know
18
Is
the assumption x is a rational number is false.
Thus, V7+ is
an irrational number
a rational number
