dH = 1.06 x 10⁻¹⁰ m

Explanation:

Scientific notation is a way of minimizing large figures in smaller decimal form. For example, 2300000 is a large figure so, its size can be minimized by converting it into scientific notation form, 2300000 can also be written as 2.3 x 106.

There are number of formats to write dH=1.06*10-10m in scientific notation by shifting the decimal in right or left direction. For example, if we shift the decimal in right direction, the addition of + 1 will occur in the power of 10 i. e. 1.06 x 10-10 will become 10.6 x 10-11 or 106 x 10-12 (these formats of scientific notation are also correct).

In some softwares and programming languages, scientific notation are written as 1.06E-10 so, avoid using these kinds of notations since, E indicates as variable in mathematics.

Variables are alphabetical value in an equation. For example, in equation 2a + 3b, a and b are variables while 2 and 3 are constants.
