What is the product of 2.5 × 10−15 and 3.9 × 1026? 6.4 × 101 9.75 × 1011 6.4 × 1041 9.75 × 1041

. We begin by multiplying the "regular" numbers first. 2.5 × 3.9 = 9.75. That's good; it's already in the proper format for scientific notation. Now we multiply the bases of 10 with their exponents. Since the bases are both 10, they are like. When we multiply like bases, we add their exponents. . Our answer then is . There you go!
