Answer :
The size of a flu virus in standard form is 1.3 × 10⁻⁷ meters.
The size of a flu virus is approximately 0.000 000 13 meters. To express this value in standard form, we can rewrite it in scientific notation.
Scientific notation is a way of representing numbers that are too big or too small to be conveniently written in decimal form. In this notation, numbers are written as a product of two numbers: a coefficient and a power of 10. The coefficient is a number between 1 and 10, and the power of 10 shows how many places to move the decimal point.
For the flu virus size, we can rewrite it as: 1.3 × 10⁻⁷ meters. Here, 1.3 is the coefficient and -7 is the power of 10. This indicates that the decimal point should be moved 7 places to the left to get the original number.
