Charles is reading about computers. He learns that a computer processor can perform one command in approximately 0.000000016

ella [17]

The number 0.000000016 is expressed in scientific notation is:

$1.6 \times 10^{-8}$

Solution:

Given that,

Charlie learns that a computer processor can perform one command in approximately 0.000000016 nanoseconds

We have to express in scientific notation

Step 1:

Given number is:

0.000000016

Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point

Here,

Move the decimal 8 places to the right to get 1.6

We have moved the decimal to left, therefore, exponent is negative

$1.6 \times 10^{-8}$

Thus the given number is expressed in scientific notation
