What is the exponent of a number?
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
What is 100 as an exponent?
We use exponential notation to write repeated multiplication, such as 10 • 10 • 10 as 103. The 10 in 103 is called the base. The 3 in 103 is called the exponent. The expression 103 is called the exponential expression….
| Exponential Form | Expanded Form | Value |
|---|---|---|
| 103 | 10 • 10 • 10 | 1,000 |
| 102 | 10 • 10 | 100 |
| 101 | 10 | 10 |

How do you explain exponents to a child?
An Exponent is a number that states how many times the base number is to be used in multiplication. The Exponent Number appears on the top right of the base number as a small number.
How do you write 1000 in exponential form?
To represent a number that’s a power of 10 as an exponential number, count the zeros and raise 10 to that exponent. For example, 1,000 has three zeros, so 1,000 = 103 (103 means to take 10 times itself three times, so it equals 10 x 10 x 10).
What does exponent mean in math?
Definition of exponent 1 : a symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power. 2a : one that expounds or interprets.
How do you find an exponent?
The base B represents the number you multiply and the exponent “x” tells you how many times you multiply the base, and you write it as “B^ x.” For example, 8^3 is 8X8X8=512 where “8” is the base, “3” is the exponent and the whole expression is the power.
