calculate y = log_10(x) where x = 0.3

just use your "log" key on your calculator.

If all you have is "ln" then log_10(0.3) = ln(.03)/ln(10)

what do you get?

Thanks Steve, I didn't know how to use this function on the calculator.

To calculate y = log_10(x) where x = 0.3, you need to use a scientific calculator or any calculator that has a logarithm function. Here are the steps to follow:

1. Turn on your calculator and locate the "log" or "logarithm" button. On most calculators, it is typically labeled as "log" or "log10" for base 10 logarithm.

2. Enter the value of x in the calculator. In this case, enter 0.3.

3. Press the "log" or "log10" button. Your calculator will then calculate the logarithm of 0.3 to the base 10.

4. The result displayed on the calculator will be the value of y. In this case, it will be approximately -0.5229.

Therefore, y = log_10(0.3) ≈ -0.5229.
