How to solve for x using logs
WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The … 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.

To evaluate log8128, let log8128 = x Then by definition of the logarithm, 8x = 128 Since 8 = 23 and 128 = 27, we obtain (23)x = 27 23x = 27 If two exponentials with the same base are equal, then their exponents must be equal. Hence, 3x = 7 x = 7 3. Check: If x = 7 3, then 8x = 87 3 = (81 3)7 = 27 = 128. Share.
