Final answer:
There is no value of the variable I that would make the given rational expression undefined.
Step-by-step explanation:
To find the values of the variable I for which the rational expression 70+5/22+52+6 is undefined, we need to determine the values of I that would result in a division by zero.
Since division by zero is undefined, we need to find the values of I that would make the denominator of the rational expression equal to zero.
Simplifying the expression, we have (22+52+6)/(70+5). To find the values of I that would make the denominator zero, we set 70+5=0 and solve for I. However, there is no value of I that can make the denominator zero.
