Question

The thickness of a soap bubble is about 0.000004 m . Write the thickness in scientific notation = 4×10^-6 m . Pls explain with step by step explanation . I am stuck ​

Answer 1

0.000004 = 4 × 10^-6 = 4 micrometer

Answer 2

See scientific notation basically means simplifying a decimal and writing it with the help of powers of 10

let’s take an example
Write 0.001 in scientific notification

so it will be 1 x 10^-3
because 10^-3 will push it three values back to its original value

similarly
0.000004 in scientific notation is
4 x 10^-6

One more example
0.00234 in scientific notation
Now this will be 2.34 x 10^-3

last one
0.01002
This will be 1.002 x 10^-2

If it’s still unclear search on YT scientific notation in units and measurements
You’ll find something helpful
