in other words: x÷2=6÷5
so x=6×2÷5=12/5=2.4

The mass of a textbook is approximately 0.00165 metric ton. How is this number written in scientific notation?
Juli2301 [7.4K]

Answer:

B) 1.65 × 10⁻³

Step-by-step explanation:

A number in <em>scientific notation</em> has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the <em>coefficient.</em>

n is an integer and is called the <em>exponent</em>.

To convert a small decimal number to exponential notation, you move the decimal point to the right until you have one nonzero digit in front of the decimal point.

The exponent is negative of the number of places you moved the decimal point.

To convert 0.001 65 to scientific notation:

Move the decimal point to the right until it is just past the 1. The coefficient is 1.65

Count the number of places you have moved the decimal (three). The exponent is -3.

The number in scientific notation is 1.65 × 10⁻³.
