2 to the power of 20 is written as: 220
2 to the power of 20 divided by 4 to the power of 10 is equal to one.
202 / 502 = (20/50)2 = (2/5)2 = 4/25 = 0.16
1,048,576
That is correct.
2^20
2 to the power 0 or 20 is equal to 1
36 - 16 = 20
The logarithm of 20 to the power of 2 is written as log(20^2). Using the power rule of logarithms, this can be simplified to 2log(20). Further simplifying, the logarithm of 20 is approximately 1.3010 (to 4 decimal places), so 2log(20) is equal to 2*1.3010 = 2.6020.
(20-1-6-2)2 = 112 = 121
The power required to do 20 joules of work in 2 seconds is 10 watts. This is calculated by dividing the work done (20 joules) by the time taken (2 seconds). Therefore, the power = Work / Time = 20 J / 2 s = 10 W.
220 = 1,048,576
