Step-by-step explanation:
Power and Exponent Definition
Power: In Mathematics, the term ‘power’ defines the raising a base number to the exponent. It denotes that the two basic elements of powers are “base number” and “exponent”. Base Number is defined as a number which is multiplied by itself, whereas the exponent represents the number of times the base number is multiplied. In short, power is a number expressed using the exponents. It implies the repeated multiplication of the same factor. Some special terms are used in the case of powers are:
When a number is:
Squared – power is 2
cubed – Power is 3
“to the power of” – used for powers more than 3
Exponent: In mathematics, the exponent is defined as a small number, which is positioned at the up-right of the base number. An exponent can be constants, numbers or any variables. Exponents represent how many times the base number has to be multiplied itself. Usually,l the large numbers are expressed using the exponents. This process is known as the raising to a power.
We can see exponents terms in many scientific notations to denote the large numbers as the powers of 10. Example: the distance between the earth and the sun is expressed in terms of an exponent is 1.50 × 108 km. Also, there are some important rules while performing some arithmetic operations with exponents.
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
Power denotes the repeated multiplication of a factor and the number which is raised to that base factor is the exponent.
