How do you find energy with power and time?
Electrical Energy = Power x Time. The total amount of electrical energy used depends on the total power used by all your electrical devices and the total time they are used in your home. One kilowatt hour is equal to 1000 watts of power used for one hour of time.
What is anything to the negative 1 power?
The negative power will become just “1” once I move the base to the other side of the fraction line. Anything to the power 1 is just itself, so I’ll be able to drop this power once I’ve moved the base.
What is 0 to the power of negative 1?
Strictly speaking we say 0−1 is undefined. x−1 is the multiplicative inverse of the number x. By definition of the multiplicative inverse, the product of a number and its multiplicative inverse equals one. So we would have 0×0−1=1.
Is there a more efficient method for raising a power to a power?
Products and Quotients Raised to Powers. The rules of exponents are very useful when simplifying and evaluating expressions. When multiplying, dividing, or raising a power to a power, using the rules for exponents helps to make the process more efficient.
Is a negative number to the zero power 1?
Will the answer be 1 for both? Answer: As already explained, the answer to (-1)0 is 1 since we are raising the number -1 (negative 1) to the power zero. However, in the case of -10, the negative sign does not signify the number negative one, but instead signifies the opposite number of what follows.
Is 1 raised to any power always 1?
The reason it is always one because “to the power of” just means how many times you would multiply the number by itself. This is the reason 1 to the power of any number is 1.
What is 2 The Power of 0?
The rule is that any number raised to the power of 0 equals to 1. So if 2 or 1,000,000 is raised to the power of 0 it equals 1.
What is 5 to the zeroth power?
Well, we know that any number divided by itself equals one. We can also apply the quotient of powers law and subtract the 3 from 3, this expression simplifies to 5 to the zeroth power. Therefore, we can see that 5 to the zeroth power equals one.
What is 10 to the second power mean?
Take exponents, for example, like writing 10 to the 2nd power. What does this mean? The first way to express 10 to the second power is to write two 10s with a multiplication sign in between, like this: 10 x 10. This indicates two factors (ie – second power) of 10 multiplied by itself.
What does 2nd power mean?
second power – the product of two equal terms; “nine is the second power of three”; “gravity is inversely proportional to the square of the distance” square. number – a concept of quantity involving zero and units; “every number has a unique position in the sequence”
How do you convert 10 to power?
Any number can be expressed in the form 10^x. This way it’s very easy to determine and compare the orders of magnitude of various numbers. For example, 1000 = 10^3, 0.01 = 10^(-2), and 1 = 10^0. However, if the number is not an even power of ten, then you’ll get a decimal fraction in the exponent.
What is 10 to the third power mean?
10 to the third power, or 10 cubed, is equal to 10 times 10 times 10. 100 × 10 {\displaystyle 100\times 10} 10 times 10 equals 100.
How do you explain exponents to the zero power?
So when we raise a number to the zeroth power, that means we multiply the number by itself zero times – but that means we’re not multiplying anything at all!
What does 10 to the power of minus 4 mean?
10 to the negative 4th power is 0.0001 or 1/10000. The negative in the exponent can be removed by making a fraction, with 1 as the numerator.
