Question

Write 205,100,000 in scientific notation

Answer 1

`\text{ 2.051}*10^8`Step-by-step explanation:

To write a number in scientific notation, we start counting from the last number by the right towards the first number by the left.

The scientific notation:

`\begin{gathered} 2.051\text{ }*10^{number\text{ of movement of the point}} \\ number\text{ of movement of the point = 8} \\ \text{The power is positive because we are moving from right to left} \\ =\text{ 2.051}*10^8 \end{gathered}`
