Can a raised integer exponent result in a rational number

The answer is the second option, which is: Marcus is correct. If any integer is raised to any integer exponent, the base is multiplied times the exponent. The product of two integers is always a rational number.

The explanation for this answer is shown below:

By definition, the set of integers contains the positive numbers, negative numbers and the zero. The rational numbers are those numbers that can be written as a fraction.

The number is an integer, but also can be written as . Then, it is a rational number too.

If it is raised to the integer exponent , it means that you must multiplied the number twice. The result will be an integer, which you can write it in the form of a fraction with as its denominator:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
