Question

Multiply 0.00032 cm by 4.02 cm and express the answer in scientific notation. Remember to follow significant figure rules.

Answer 1

im guessing it is 1.3 X 10 -3 cm squared

Answer 2

when multiplying decimals you keep the lowest number of significant figures as the number of sig figs originally. for scientific notation move the decimal point to the right, count how many decimal places you moved, and think in terms of whether you made the number bigger or smaller in scientific notation. if you made it smaller the scientific exponent should be positive. if it was made bigger than it really is the scientific exponent should be negative. now give me a medal.
