Answer 2

Concept

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation.

Given

The number in decimal form is given which is 0.000000789

Find

We have to find standard form of given decimal number

Solution

The steps are as follow:

• After moving the decimal point immediately after the first non-zero integer, in this example 7
• We wish to eliminate all the non-significant zeros.
• In order for our exponent to be negative, we must move the decimal point seven spaces to the right.
• We would have gotten a positive exponent if the decimal had shifted left.
• So the answer will be 7.89 × 10^(-7)

Hence the standard form of 0.000000789 will be7.89 × 10^(-7)
