1. Calculate the product:

0.025 x 16000 = 400

2. Express in scientific notation:

Scientific notation is written as a number between 1 and 10 multiplied by a power of 10.

* Move the decimal point in 400 two places to the left to get 4.00.

* Since we moved the decimal two places to the left, the power of 10 is 2.

Therefore, 0.025 x 16000 in scientific notation is 4.00 x 10²
