To understand the expression "1.2 x 10^3," we need to know that this is a way to represent a number in scientific notation.

In scientific notation, a number is written in the form of "a x 10^n," where "a" is a number greater than or equal to 1 but less than 10, and "n" is an integer exponent. This notation is used to write very large or very small numbers in a more concise form.

So, in the expression "1.2 x 10^3," the base number "a" is 1.2, and the exponent "n" is 3. This means that we need to multiply 1.2 by 10 raised to the power of 3.

To calculate the value, we can multiply 1.2 by 10 three times:

1.2 x 10^3 = 1.2 x (10 x 10 x 10) = 1.2 x 1000 = 1200.

Therefore, "1.2 x 10^3" is equal to 1200.
