Vanier College Sec V Mathematics Department of MathematicsWorksheet: Logarithmic Function 1. Find the value of y. ( 1) log 5 25 = y ( 2) log 3 1 = y ( 3) log 16 4 = y ( 4) log. What is log in Algebra? How to use logarithm tables? Divide by a power of ten: For evaluating the given log expression, the square root of 2 can be written in exponential notation as 2 raised to the power of. Understand how to multiply numbers using their logarithms. In algebra, “ log” is short for “ logarithm. ” Logarithms are the opposites, or inverses, of equations involving exponents, like y = x^ 3. In their simplest form, logs help to determine how many of one number must be multiplied to obtain another number. Logarithms were initially invented to help people solve lengthy.

This is generally pronounced “ log base b of y is x. ” It is equivalent to the exponential equation y = b^ x, in which “ b” represents the base number and “ x” represents the exponent. In any logarithm, the base, b, must be greater than zero and cannot equal one. How to evaluate logarithms? b) Without tables, simplify 2log10 5+ log10 8 log10 2.
