## How do you get rid of DEC on a scientific calculator?

Explanation:

- TI models: Press [SCI/ENG]. The display shows FLO SCI ENG. Use the left arrow key to select FLO.
- Casio models: Press [SHIFT][MODE][6:Fix]. You are then prompted to enter a number between 0 and 9.
- Sharp models: Press [SET UP] [1:FSE] [0:FIX]. This sets the calculator to use a fixed number of decimal places.

**Can you multiply logs with the same base?**

What is the rule when you multiply two values with the same base together (x2 * x3)? The rule is that you keep the base and add the exponents. Well, remember that logarithms are exponents, and when you multiply, you’re going to add the logarithms. The log of a product is the sum of the logs.

### What is the log of base 2?

Log base 2, also known as the binary logarithm, is the logarithm to the base 2. The binary logarithm of x is the power to which the number 2 must be raised to obtain the value x. For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1 and the binary logarithm of 4 is 2.

#### How to write log base?

Type a logarithm in Excel. Open the spreadsheet and click the cell in which you want to insert the logarithm. Type the formula “=log (number, base),” replacing the number and base by numeric values of the logarithm. If the base is kept blank, then Excel will assume that the base of the logarithm is “10.”

**What is the formula for log?**

Logs are described symbolically by the equation log(b)(y) = x. 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.
