Convert from Radical to Exponential Form: Remember the index (root) of the radical will become the denominator of the fractional exponent, and the power will become the numerator. Create the denominator first and then the numerator. Create the numerator first and then the denominator.

Section 1-3 : Radicals. where n is called the index, a is called the radicand, and the symbol √ is called the radical. The left side of this equation is often called the radical form and the right side is often called the exponent form.

Explanation: When dividing exponential expressions with the same base, subtract the exponents. In this problem, the exponents are and . When subtracted, the result is .

Remember that the original exponential formula was y = abx. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.

In MATLAB the function exp(x) gives the value of the exponential function ex. Find the value of e. e = e1 = exp(1). MATLAB does not use the symbol e for the mathematical constant e = 2.718281828459046.

Product of a Power: When you multiply exponentials with the same base, you add their exponents (or powers). Power to a Power: When you have a power to a power, you multiply the exponents (or powers). Quotient of Powers: When you divide exponentials with the same base, you subtract the exponents (or powers).

Multiplying Radical Expressions You can simplify this square root by thinking of it as . If you think of the radicand as a product of two factors (here, thinking about 64 as the product of 16 and 4), you can take the square root of each factor and then multiply the roots. The end result is the same, .

Squaring or raising to the second power the square root term should eliminate the radical. However, you must do it to both sides of the equation to keep it balanced. Make sure that you verify the domain and range of the inverse function from the original function. They must be “opposite of each other”.

Writing numbers based upon powers of ten is called exponential notation. Because exponential notation is used a great deal by scientists, it is also called scientific notation. Exponential notation and scientific notation are two names for the same thing.

If a quantity is written as the product of a power of 10 and a number that is greater than or equal to 1 and less than 10, then the quantity is said to be expressed in standard form (or scientific notation). It is also known as exponential form. Note that we have expressed 65 as a product of 6.5 and a power of 10.

A logarithmic equation is an equation that involves the logarithm of an expression containing a variable. To solve exponential equations, first see whether you can write both sides of the equation as powers of the same number.
