The equation x = 2y is often written as a logarithmic function (called log function for short). The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base.... Logarithmic FormExponential Formlog5 5 = 151 = 54-1 =10-2 = 0.012 more rows

Solving Logarithmic Equations Step 1: Use the rules of exponents to isolate a logarithmic expression (with the same base) on both sides of the equation. Step 2: Set the arguments equal to each other. Step 3: Solve the resulting equation. Step 4: Check your answers. ... Solve.

Logarithmic Function Definition In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as. For x > 0 , a > 0, and a ?1, y= loga x if and only if x = ay.

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

The process of converting from exponential to log form is a simple process. The exponential form ax=N a x = N is converted to logarithmic form logaN=x l o g a N = x , and this simple formula is helpful to convert exponential to log form.

The "basic" logarithmic function is the function, y=logbx, where x, b>0 and b?1.
