Exponents are also known as Indices or Powers. The exponent of numbers informs the user as to how many times they need to be used in multiplication. For example 82 = 8 x 8 or 64. In this case, 82 is also called as the second power to 8 or 8 to the power 2 or it can also be known as 8 squared. Exponents help in saving the time of writing a lot of multiples. For example, a5 would ideally have had to be written as a x a x a x a x a= aaaaa The rules of exponent states that negative exponents means dividing since dividing is the opposite of multiplying and fractional exponents means taking the nth root. The exponent calculator is used to calculate answers of a number which is the base number to it’s nth power. This includes all kinds of exponential expressions, negative bases and more. An exponent is actually the small number which is denoted in the right upper position of the base number. This informs of the power which the expression is to be raised to. For example 53denotes 5 x 5 x 5 = 125.
Exponents which are negative like 4-3 can be denoted as 1 divided by 43 which means 1 divided by 64 or 0.015625 If there are negative bases which are present in the exponential expressions then what one needs to be aware of is where the negative sign is. Whether it is in the parenthesis or whether it is out of it. For example : If -4 is not in the parenthesis and this is raised to the power 4, it would mean -1 x 4 x 4 = -16 -1 x 4 x 16 = -64 -1 x 4 x 64 = -256 Whereas in the parenthesis the same (-4)4 means -4 x -4 = 16 -4 x 16 = -64 -4 x 64 = 256 The rules to exponential expressions are that: a) if the bases that are multiplied are identical, then they can be combined into a single expression by adding them. b) If the bases which are divided are identical, then they can be combined into the same expression by subtracting them. c) When there is an exponential expression which is further raised to a power, then the exponents have to be multiplied. d) If there is any variable or number which is raised to zero, the answer is 1 Exponents are used in everyday life. In fact we use units such as square foot, square inches, square meters and more when you are calculating the area of a carpet or the size of the room. In computer terms, we hear megabytes which stands for 109 and terabytes which stands for 1012. We hear megahertz which is 106 or one million hertz. The an exponent calculator helps to save the time of the user, and they are especially helpful when a large amount of calculations need to be done, or the exponential value is huge.
