Question

Write the following numbers in Scientific Notation:

a. 2.5 x 10^12
b. 2.3 x 10^-4
c. 1.01 x 10^2
d. 3.2 x 10^-9
A. a: 2.5 x 10^12, b: 2.3 x 10^-4, c: 1.01 x 10^2, d: 3.2 x 10^-9
B. a: 2.5 x 10^-12, b: 2.3 x 10^4, c: 1.01 x 10^-2, d: 3.2 x 10^9
C. a: 25 x 10^11, b: 0.023 x 10^-3, c: 101 x 10^0, d: 32 x 10^-8
D. a: 25 x 10^11, b: 23 x 10^-5, c: 1.01 x 10^2, d: 32 x 10^-9

Answer 1

Each of the numbers in scientific notation are:

a) 2.5 *
`10^(12)`

b) 2.3 *
`10^(-4)`

c) 1.01 *
`10^(2)`

d) 3.2 *
`10^(-9)`

How to write the numbers in Scientific Notation?

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 750,000,000 can be written in scientific notation as 7.5 * 10
`.^(8)`

a) 2.5 *
`10^(12)`

This is already in scientific notation as it fulfills the definition of scientific notation.

b) 2.3 *
`10^(-4)`

This is already in scientific notation as it fulfills the definition of scientific notation.

c) 1.01 *
`10^(2)`

This is already in scientific notation as it fulfills the definition of scientific notation.

d) 3.2 *
`10^(-9)`

This is already in scientific notation as it fulfills the definition of scientific notation.
