# How is 438,500,000,000 written in scientific form?

Mar 8, 2018

4.385 $\times {10}^{11}$

#### Explanation:

In Scientific notation there is only one digit to the left of the decimal point. The other significant digits are written to the right of the decimal point. Then the digits are multiplied by a power of ten. The multiplication of the power of ten establishes the value of the digits and acts as the place holder.

In 4 38,500,000,000 The four is written to the left of the decimal point. 385 are significant numbers and are written to the right of the decimal point, 00,000,000 are zero's used as place holders and are not significant. The power of ten will replace the zero's as place holders.

In 438,500,000,000 there are 11 places between the four and the last zero. This is equal to 10 to the 11th power so

$4.385 \times {10}^{11}$
