What are five examples of scientific notation?

Here are five examples:

  • Multiply (4 x 104) and (7 x 105) First 4 x 7 = 28. Next add exponents, 4 + 5 = 9. Result is 28 x 109
  • Divide (6 x 105) by (4 x 104) 6/4 = 1.5. Subtract exponents 5 – 4 = 1. Answer 1.5 x 101 or 15.
  • Multiply (4 x 10-7) and (3.25 x 109) 4 x 3.25 = 13. Add exponents = -7 + 9 = 2. Answer is 13 x 102 or 1300.

What is an example of a correct scientific notation?

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. Created by Sal Khan and CK-12 Foundation.

How do you convert standard notation to scientific notation?

To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates.

What is an example of scientific notation you see in everyday use?

It’s easier to read and write very big or very small numbers using scientific notation. For example, the $65,000,000,000 cost of Hurricane Sandy is written in scientific notation as \begin{align*}\$6.5 \times 10^{10}\end{align*}.

How do you write 1.5 in scientific notation?

The number 10 is called the base because it is this number that is raised to the power n. Although a base number may have values other than 10, the base number in scientific notation is always 10….1.5: Scientific Notation – Writing Large and Small Numbers.

Explanation Answer
d Because the decimal point was moved four places to the left, n = 4. 1.2378×104

How do you add and subtract in scientific notation?

To add or subtract two numbers in scientific notation: Step 1: Adjust the powers of 10 in the 2 numbers so that they have the same index. Step 2: Add or subtract the numbers. Step 3: Give the answer in scientific notation.

How do you calculate scientific notation?

Scientific to decimal. If using our scientific notation calculator, you have two options. You can either enter a single e-notation number in the first field, and press “Convert”, or you can enter the significand in the first field and the exponent in the “Exponent” field, then press the button.

How to multiply scientific notation?

If the numbers are not in scientific notation,convert them.

  • Regroup the numbers using the commutative and associative properties of exponents.
  • Now multiply the two numbers written in scientific notation,you work out the coefficients and the exponents separately.
  • Use the product rule; b m x b n = b (m+n) to multiply the bases.
  • Join the new coefficient to the new power of 10 to get the answer.
  • If the product of the coefficients is greater than 9,convert it to scientific notation and multiply by the new power of 10.

    • What are the rules for scientific notation?

    SCIENTIFIC NOTATION RULES. RULE #1: Standard Scientific Notation is a number from 1 to 9 followed by a decimal and the remaining significant figures and an exponent of 10 to hold place value. Example: 5.43 x 102 = 5.43 x 100 = 543 8.65 x 10 – 3 = 8.65 x .001 = 0.00865 ****54.3 x 101 is not Standard Scientific Notation!!!
