Why is a number to the first power equal that number?

For positive integer exponents, the exponent tells you how many times to take the base (the number being raised) as a factor then multiply. So x^3 = x * x * x (3 times). x^2 = x * x (2 times). x^1 = x (1 time). For negative exponents, do the same thing, but then take the reciprocal (1 divided by the number) to get the answer. Exponent of zero is defined to equal 1, for any nonzero base number. Rational exponents equate to taking a root (square root for 1/2, cube root for 1/3, etc). Irrational exponents cannot use these methods, but require using logarithms to solve.

How do you raise a exponent?

In the simplest case - a positive integer exponent - the exponent is an indicator of how often a number should be used as a factor. For example, 25 means that the number 2 should appear five times as a factor: 2 x 2 x 2 x 2 x 2. Exponentiation is also defined for an exponent of zero, negative exponents, and fractional exponents, but be sure to understand this simplest case first.


What is the definitions for exponents?

In the number x, with positive integer exponent a, a is the number of times that 1 (not the number itself) is multiplied by x. So, for example in the expression, 43 the exponent is 3 and the number represented is "1 is multiplied by 4 three times". If you multiply 4 by itself 3 times, you will get 4*4 (one time) * 4 (two times) *4 (three times) and that is NOT 43: it is just a wrong description.The laws of exponents are:xa * xb = xa+bxa / xb = xa-b(xa)b = xa*b(xy)a = xa * yaThe first three are used to extend the domain of exponents to negative integers and rational numbers. Exponents to irrational numbers are defined as limits of the exponents of the rational sequences converging to the irrational number.Finally, 00 is not defined (because it does not converge).

A positive number minus a positive number is always positive?

no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2


Is a negative subtracted from a positive will it be a positive answer?

Yes. to subtract a negative is to add that number, so the number will be higher than the first number which is positive and can't go below zero.


What is a positive number minus a negative number?

a negative number minus a negative number is a negative number plus a negative number the answer depends on the value of the first number if the first number's absolute value is larger than the second number's absolute value than the answer is negative if the first number's absolute value is less than the second number's absolute value than the answer is positive


What is the first positive non Fibonacci number?

Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
