In physics, power is the rate of doing work, the amount of energy transferred per unit time having no direction, it is a scalar quantity in the international system of units, the unit of power is the joule per second (j/s), known as the watt in honour of james watt, the eighteenth-century developer of the steam engine condenser. Power is work or energy divided by time, so power has the units of joules/second, which is called the watt — a familiar term for just about anybody who uses anything electrical you abbreviate a watt as simply w, so a 100-watt light bulb converts 100 joules of electrical energy into light and heat every second. Best answer: power means how many times you want to multiply a number by 1 or itself if you say 2 to the power 4 means multiply 2 four times by 1 2^4 = 12222. Exponents the exponent of a number says how many times to use the number in a multiplication in 8 2 the 2 says to use 8 twice in a multiplication, so 8 2 = 8 × 8 = 64 in words: 8 2 could be called 8 to the power 2 or 8 to the second power, or simply 8 squared.
It breaks you out of just thinking one way, said teresa lesiuk, an assistant professor in the music therapy program at the university of miami dr lesiuk's research focuses on how music. Figuring out 10 to the power of any positive integer is easier than it looks all you have to do is know that the exponent above the number 10 simply indicates the number of times that you have to multiply 10 by itself. The power rating indicates the rate at which that machine can do work upon other objects thus, the power of a machine is the work/time ratio for that particular machine a car engine is an example of a machine that is given a power rating.
Thus, when a number to some power is raised to a power again, we multiply the two powers to get the resultant value: (2 3 ) 2 = 2 (3) × (2) = 2 6 finally, one more important piece of knowledge about exponents: a number raised to the power of zero is alwasy equal to 1.
