Exercise 54 Page 16

Start with finding the value of I.

Rational numbers.

To determine which set of numbers best describes the value of I, let's first substitute the values W= 50 and R= 200 into the formula. Then we can find the value of I and describe it.
I=sqrt(W/R)
I=sqrt(50/200)
I=sqrt(1/4)
I=1/2
The value of I is a fraction that cannot be simplified further. Therefore, we can say that it belongs to the set of rational numbers.
