Always remember: dividing by a number is the same as multiplying it by it's inverse. Example: 10/2 is the same a 10*1/2=5. 20/4 is the same as 20*1/4=5. If you want to multiply instead of divide, just take the inverse or reciprocal of the number you want to divide by. on the wings love lyrics

WebAn exponential equation is an equation in which the variable appears in an exponent. A logarithmic equation is an equation that involves the logarithm of an expression … WebCommon Logarithms: Base 10. Sometimes a logarithm is written without a base, like this: log(100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number.
