ANSWER
SCIENTIFIC NOTATION Is in the form c x 10n
C is a number between 1 and 9.99……….
n is an integer Positive = bigger number (move right) Negative = smaller number (move left)
SCIENTIFIC NOTATION Examples…
Ex 1) 1,200
Ex 2) 0.0004
Ex 3) 31,200,000
Multiplying Scientific Notation Examples…
Ex 4) (3.2 x 103) (1.4 x 102)
Ex 5) (2.7 x 104) 2
Ex 6) (2.2 x 10-5) (7.4 x 103)
