Hope it will help :)

Final answer:

The number 1.452 x $10^3$ in scientific notation can be written as the ordinary number 1452 by shifting the decimal point three places to the right.

Explanation:

The given number is in scientific notation and we need to convert it into an ordinary number. It uses a decimal number between 1 and 10 (inclusive) and multiplies it by a power of 10.

In the given expression 1.452 x $10^3$ , the $10^3$ means we need to shift the decimal place in 1.452 three places to the right. This is because the exponent is positive. After shifting, the number becomes 1452.
