Write 0.0000002711 in scientific notation. (Use 2 numbers after the decimal point.)

Step-by-step explanation:

Given

Required

Write, using scientific notation

The scientific notation is written in the form:

 Where n is an integer and

To start with; Represent the given number as fraction

Represent the denominator as an exponent

This can be rewritten in form of:

Remember that:  Where n is an integer and

This implies that; we need to adjust 2711 to a number between 1 and 10;

This gives:

Write 1000 as an exponent

Apply law of indices

The question requires 2 numbers after the decimal point;

So, 2.711 will be approximated to 2.71

Hence;

 is equivalent to

the correct answer is the second option

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
