0.07 nm is represented by scientific counting method
0.07nm = 0.07 * 10 ^ (- 9) = 7 * 10 ^ (- 11). This is the representation of a significant number. If it is two significant numbers, it is 7.0 * 10 ^ (- 11), three significant numbers are 7.00 * 10 ^ (- 11), and so on, but it cannot be written as 70 * 10 ^ (- 10)
123.5 expressed by scientific counting method
123.5=1.235×10²
Use scientific counting method to express the following numbers 123.56=
123.56 = the second power of 1.2356 × 10
