154 = 15 x 15 x 15 x 15 = 50625
10 to the 4th power is 10,000
== A number to the second power means 'squared,' so it is 15 x 15, which is 225. == 15 to the second power is nothing but 15 squared.152 = (15 * 15) = 225. Therefore 15 to the second power is 225.225
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
25 to the 2nd power, 5 to the 4th
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
10 to the 4th power is 10,000
18 to the 4th power is 104976

2 to the 4th power times 5 to the 3rd power = 2,000
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
== A number to the second power means 'squared,' so it is 15 x 15, which is 225. == 15 to the second power is nothing but 15 squared.152 = (15 * 15) = 225. Therefore 15 to the second power is 225.225

Three to the 4th power divided by 3 to the 7th power equals 0.03703703703
1.657 times 10 to the 4th power = 16,570
15 to the negative 5th power as a fraction can also be written as 1/15 to the 5th power.
15-4/155 = 15-9 or 1/159
15 to the power of 0 = 1
