To multiply numbers in scientific notation, first multiply the coefficients . Then, add the exponents of the two numbers and keep the base 10 the same. For example (2 x 10^6) (4 x 10^8) = 8 x 10^14.
How do you simplify exponents in scientific notation?
To multiply numbers in scientific notation, first multiply the coefficients . Then, add the exponents of the two numbers and keep the base 10 the same. For example (2 x 10^6) (4 x 10^8) = 8 x 10^14.
How do you do scientific notation expressions?
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.
What are the 5 rules of scientific notation?
| Rule #1 The base is always 10 | Rule #3 The absolute value of the coefficient is greater than or equal to 1 but less than 10 | Rule #4 The coefficient carries the sign (+) or (-) | Rule #5 The mantissa carries the rest of the significant digits |

What are the rules of scientific notation?
Scientific Notation Rules:
The scientific notations are written in two parts one is the just the digits, with the decimal point placed after the first digit, followed by multiplication with 10 to a power number of decimal point that puts the decimal point where it should be.
How do you convert numbers to scientific notation?
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit . Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
What is the general formula of scientific notation?
Scientific notation is a more convenient way of writing very small or very large numbers. The general representation for scientific notation is a×10b a × 10 b (where “b” is an integer and “a” is any real number).
Where is scientific notation used?
Scientific notation is used to write numbers that are too big or too small to be conveniently written in decimal form .
How do you write 0.00345 in scientific notation?
0.00345 would be written as 3.45×10 – 3 in scientific notation.
What is 10 to the scientific notation?
| Powers of 10 | 10−5= 0.00001 101=10 | 10−2=0.01 104=10,000 | 10−1=0.1 105=100,000 | 100=1 106=1,000,000 |

How do you write 125000 in scientific notation?
125,000 (one hundred twenty-five thousand) is an even six-digits composite number following 124999 and preceding 125001. In scientific notation, it is written as 1.25 × 10 5 .
How do you convert to standard form?
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
How do you convert scientific notation to decimal?
- Determine the exponent, n , on the factor 10 .
- Move the decimal n places, adding zeros if needed. If the exponent is positive, move the decimal point n places to the right. If the exponent is negative, move the decimal point |n| places to the left.
- Check.
