So to multiply standard form we multiply the 2 numbers and the 2 indices separately. 2.6*3.9=10.14 x^2 * x^11 = x^13 So we've got 10.14*10^13 However Standard form must be 1≤x≤10 therefore we need to divide that by 10 but to get the same number we add one onto the power of 10. So the answer is: 1.014*10^14 lbs of oxygen are produced in the rainforest each year.
