The definition of exponentiation can be extended in a natural way (preserving the multiplication rule) to define for any positive real base and any real number exponent . More involved definitions allow complex base and exponent, as well as certain types of matrices as base or exponent.
As the number of compounding periods tends to infinity in continuous compounding, the continuous compound interest rate is referred to as the force of interest . For any continuously differentiable accumulation function a(t), the force of interest, or more generally the logarithmic or continuously compounded return , is a function of time as ...
The Power of Compounding You might be amazed by how quickly your penny can grow into one million dollars. It can reach five million dollars and, then finally, on day 31, more than $10.7 million.
Here’s what the letters represent: A is the amount of money in your account. P is your principal balance you invested. R is the annual interest rate expressed as a decimal. N is the number of ...
Plain text, programming languages, and calculators also use a single asterisk to represent the multiplication symbol, [6] and it must be explicitly used; for example, 3x is written as 3 * x. Rather than using the ambiguous division sign (÷), [ a ] division is usually represented with a vinculum , a horizontal line, as in 3 / x + 1 .
If all the prime factors of a number are repeated it is called a powerful number (All perfect powers are powerful numbers). If none of its prime factors are repeated, it is called squarefree. (All prime numbers and 1 are squarefree.) For example, 72 = 2 3 × 3 2, all the prime factors are repeated, so 72 is a powerful number.
The power of a point is a special case of the Darboux product between two circles, which is given by [10] | | where A 1 and A 2 are the centers of the two circles and r 1 and r 2 are their radii. The power of a point arises in the special case that one of the radii is zero.
By comparison, powers of two with negative exponents are fractions: for positive integer n, 2-n is one half multiplied by itself n times. Thus the first few negative powers of 2 are 1 / 2 , 1 / 4 , 1 / 8 , 1 / 16 , etc. Sometimes these are called inverse powers of two because each is the multiplicative inverse of a ...
