Example Questions

Example Question #151 : Algebra

What is \(\displaystyle 15\times15\times15\times15\times15\) in exponential notation? 

Possible Answers:

\(\displaystyle 5\times15\)

\(\displaystyle 15^{5}\)

\(\displaystyle 15\times5\)

\(\displaystyle 5^{15}\)

\(\displaystyle 5\times1\)

Correct answer:

\(\displaystyle 15^{5}\)

Explanation:

Exponential notation includes a base number and an exponent. The base number is the number that is being multiplied and the exponent is how many times the base number is being multiplied to itself.

In this case, \(\displaystyle 15\) is our base number and it's being multiplied to itself \(\displaystyle 5\) times, so that is our exponent.

\(\displaystyle 2\times19\)

\(\displaystyle 19\times2\)

\(\displaystyle 2\times9\)

Correct answer:

\(\displaystyle 19^2\)

Explanation:

Exponential notation includes a base number and an exponent. The base number is the number that is being multiplied and the exponent is how many times the base number is being multiplied to itself.

In this case, \(\displaystyle 19\) is our base number and it's being multiplied to itself \(\displaystyle 2\) times, so that is our exponent.

Example Question #161 : Algebra

What is \(\displaystyle 20\times20\times20\times20\) in exponential notation? 

Possible Answers:

\(\displaystyle 4^{20}\)

\(\displaystyle 4\times20\)

\(\displaystyle 20^4\)

\(\displaystyle 4\times4\times4\times4\times4\)

\(\displaystyle 20\times4\)

Correct answer:

\(\displaystyle 20^4\)

Explanation:

Exponential notation includes a base number and an exponent. The base number is the number that is being multiplied and the exponent is how many times the base number is being multiplied to itself.

In this case, \(\displaystyle 20\) is our base number and it's being multiplied to itself \(\displaystyle 4\) times, so that is our exponent.
