change 9.61 x 10^-4 to standard
0.000961 (move decimal 4 times to make number smaller)
change 0.0000421 to scientific
4.21x10^-5 (decimal needs to move 5 times and its a small number so -)
change 5.43 x 10^2 to standard
543. (move decimal twice to make number bigger)
change 62,000,000. to scientific
6.2x10^7 (decimal needs to move 7 times and its a big number so +)
dividing scientific notation
divide the bases, write "x10" and the exponent is the difference of the 2 exponents
Scientific Notation
m x 10 ^ n m = base (number between 1 and 9.99) n = exponent (+ or -)
multiplying scientific notation
multiply the bases, write "x10" and the exponent is the sum of the 2 exponents
scientific notation with + exponent
number is bigger than 1
scientific notation with - exponent
number is smaller than 1
