Scientific Notation

Scientific notation is the expression of a number based on the largest exponent of 10 for its value, where the form is a decimal number A x 10n.

What is 420 in index form?

It is: 4.2*10^2 when in scientific notation

How do you Cube a number in scientific notation?

Whenever you have an exponent (as in scientific notation) that is raised to a power, you simply multiply the exponents to get your answer. You can think of it simply by expanding it out as in this example:

(A X 10^y)^3 = (A X 10^y) X (A X 10^y) X (A X 10^y)

Then you use the rules of multiplying exponents to solve:

= A x A x A x 10^y+y+y

= A^3 X 10^3y

Here's an example:

(1.35 X 10^6)^3 = 1.35^3 x 10^(6 X 3)

= 2.460375 X 10^18

=2.46 X 10^18 (In significant digits)

What is 6.9 in scientific notation?

It can be written as 6.9*10^0, but that is hardly worth the effort.

What is the scientific notation of There are 5 280 feet in one mile?

In scientific notation, the number is 5.28 x 10³ ft. Shift 3 decimal places to the left.

What is the power of 2x2x2x2?

2x2x2x2 = two to the fourth power (2^4).

Why is scientific notation used in science?

Because sometimes numbers get very big or very small.

Why do scientists use scientific notation?

Scientists use scientific notation because it is a convenient way of handling very large or very small numbers. Chemists, for example, use the idea of a mole, which is approximately 6.022 x 10^23 atoms or molecules of a substance. If we wrote this number out in traditional decimal notation, it would look like 602,200,000,000,000,000,000,000. Many of the constants used in physics and chemistry are also very large or very small numbers. For example, the Planck constant, important in describing the energies of quantized systems, is approximately 6.63 x 10^-34 Js. If we wrote out this number traditionally it would look like 0.000000000000000000000000000000000663.

What is 6000 in scientific notation?

6000 = 6 x 103

6000 = 6 x 1000

1000 = 10 x 10 x 10 = 103

⇒ 6000 = 6 x 103
