A leak in a water tank causes the water level to decrease by 3.6×10^−2 millimeters each second.

About how many millimeters does the water level in the tank decrease in 5 hours, or 1.8×10^4 seconds?



express the answer in scientific notation.

  1. can you not find
    1.8×10^4 ÷ (3.6×10^−2) ?

    hint: remember your exponent laws

  2. what don't you understand about "multiply the two numbers"?

    3.6×10^−2 * 1.8×10^4 = (3.6*1.8)×10^(-2+4)

  3. go with Steve's multiplication
    I picked the "wrong" special symbol, should just stick with standard keyboard keys
