Use the References to access important values if needed for this question Consider the following operations on the number 4.04 x 102 Without using a calculator, decide which would give a significantly smaller value than 4.04 × 10-2 which would give a significantly larger value, or which would give essentially the same value 4.04 × 10-2, 8.00 × 10-6 4.04 × 10-2 8.00 × 10-6 | 4.04 × 10-2 x 8.00 x 10-61 4.04 × 10-2 / 8.00 × 10-6- larger smaller same Submit Answer Retry 8 more group attempts remaining Scans 20 ver 100% | Clear

Explanation / Answer

First two calculation will give significantly same value. Since the other term is significantly very small w.r.t 4.04*10^-2

, hence adding or subtracting the latter term will have no significant affect.

4.04e-2 *8e-6 = 32.32e-8 = 3.232e-7 which is significantly smaller than our value

4.04e-2 / 8e-6 = 0.505e4 = 5050 which is significantly larger than our value
