Very large and very small numbers are easier to write in scientific notation. For example, the number, 0.0000516 would be written 5.16 10-5 in scientific notation. How would you enter this number in WebAssign using scientific notation to 3 significant figures? (WebAssign uses e-notation for entering scientific numbers, for example, 1.23e-4.)
Hemoglobin is a protein that transports oxygen from the lungs to the rest of the body. Lab results indicated a patient had a hemoglobin concentration in the blood of 14.3 g/dL, which is in the normal range. Convert the number of grams to milligrams and write the answer in scientific notation. ×10
