Exponential Form of 1000: 10^3
To express 1000 in exponential form, we need to determine the power to which the base 10 must be raised to get the number 1000.
Breaking Down the Number 1000:
- 1000 = 10 x 10 x 10
- 10 is multiplied by itself 3 times to get 1000
Writing in Exponential Form:
- 1000 can be written as 10^3
- Here, 10 is the base and 3 is the exponent
- The exponent 3 indicates that the base 10 is multiplied by itself 3 times
Final Answer:
- Therefore, the exponential form of 1000 is 10^3.
