Answer 1

Answer:

Step-by-step explanation:

4 / root 7

we take the rationalizing factor as root 7 since denominator is root 7.

4 / root 7 * root 7 / root 7    (we multiplied root 7 on both numerator and denominator since root 7 is the rationalizing factor)

this becomes 4 root 7 / 1  = 4 root 7.

thus, the denominator is rationalized to 1.
