What is the number used as a factor?
“Factors” are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15.
What do you call to a number that tells how many times the base is multiplied?
The exponent, or power, tells how many times to use the base as a factor in the multiplication. In the example, 7. 7 can be written as 72, 7 is the base and 2 is the exponent.
Which of the following refers to how many times a number is written as a factor?
The exponent is the number of times the base is used as a factor.
What is the number or expression in a power that is multiplied by itself?
In mathematics, we call multiplying a number by itself “squaring” the number. We call the result of squaring a whole number a square or a perfect square. A perfect square is any number that can be written as a whole number raised to the power of 2. For example, 9 is a perfect square.
How do you know how many factors a number has?
How to Find Number of Factors?
- Find its prime factorization, i.e. express it as the product of primes.
- Write the prime factorization in the exponent form.
- Add 1 to each of the exponents.
- Multiply all the resultant numbers.
- This product would give the number of factors of the given number.
What do you call a number that is used as a factor as many times as indicated by the exponent?
An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.
What is the result of multiplying one number by another?
The number to be multiplied is the “multiplicand”, and the number by which it is multiplied is the “multiplier”. The result of a multiplication is called a product.
How do you write repeated multiplication as a power?
To write repeated multiplication of the same number in exponential notation, first write the number being multiplied as the base. Then count how many times that number is used in the multiplication, and write that number as the exponent.
What do call to a number that is used as a factor as many times as indicated by the exponent?
A number raised to the first power is that number. For example, 101 = 10. To show the factors of a number expressed using exponents, you write the number in “expanded form”, also called factored form. We can also use the product rule to simplify expressions.
