Answer:
A rational expression that has the nonpermissible values  and
 and  is
 is  .
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of  , the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
 (1)
 (1)
Then, the factorized form of  must be:
 must be:
 (2)
 (2)
If we know that  , then the rational expression is:
, then the rational expression is:

Answer:
- multiplying a multi-digit number by itself several times (finding the power of a number)
- finding a square root
- statistical calculations
Step-by-step explanation:
We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)
If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.
___
All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.
