WebNov 3, 2024 · Calculating an exponent is as simple as multiplying the base number by itself. Learn to work with positive exponents and positive base numbers. The exponent tells you how many times to multiply the number by itself. For instance, three to the power of four, or 3 4, will be: 3 × 3 × 3 × 3 = 9 × 9 = 8 1. 3 × 3 × 3 × 3 = 9 × 9 = 81 3×3× ... WebFirstly, instantaneous power is equal to F · v. If we said that F = m · a, and plug that into the instantaneous power, then we would have P = m · a · v. So now we can see that for the power, the mass does matter. Then, the instantaneous speed is a magnitude that is constant by the simple meaning that is in an infinitesimal time interval.
