One half to the negative first power is equal to the reciprocal of one half raised to the first power. The reciprocal of one half is two, so (1/2)^(-1) = 1 / (1/2) = 1 * 2 = 2.
2 times 10 to the 3rd power = 2,000
4^.5= 2
10-2 = 0.01 (or 1/100)
You can do this with logarithms 2 to the x equals 10 to the 80 xlog2 = 80log 10 = 80 x = 80/log2 = 266 2 to the 266 power = 10 to the 80 power
"3 dB" is a nickname for "1/2 power". "1/2 power" in dB = 10 log(1/2) = 10 (-0.30103) = -3.01 dB
2 and a half plus 2 and a half plus 10 plus 10 = 25
10 to the power 8 divided by 10 to the power of 6 is 10 to the power of (8 - 2) which is 10 to the power of 2 or 100
no, 2 over 10 simplifies to 1/5, and that isn't half. 5over 10 or 2 over 4 would equal half.
It is the (-2) power.
Yes. 2^10 = 1024 10^2 = 100 1024 > 100 → 2^10 > 10^2
It is: 10/2 = 5
It is 1.7*10^8
8 to the power of 1/2 = 2.8284271247461900976033774484194 2.8284271247461900976033774484194 to the power of 2 = 8
-3db equates to half of the original power. if you had 1 watt input. and the output is 1/2 watt. The power gain is calculated by 10 log (Pin/Pout) ( in bels its log(Pin/Pout) in decibels its 10 log (Pin/Pout) ) That is 10 log (1/ 1/2) = 10 log 2 = -3 that's -3db for you It communications and in so many other fields. the 3db mark is taken as kind of datum for useful power. that is to say beyond this the magnitude will reduce below half.
10 * 1/2 = 10/2 = 5
