What is log4 19 to four right decimal places?
It is 2.1240
What is x if the question is log4 7x5?
To solve for ( x ) in the equation ( \log_4 7x = 5 ), we can rewrite it in exponential form: ( 7x = 4^5 ). Calculating ( 4^5 ) gives us ( 1024 ), so we have ( 7x = 1024 ). Dividing both sides by 7 results in ( x = \frac{1024}{7} ), which simplifies to approximately ( 146.29 ).
What is the answer to log4 (3x 5)(x-6)3?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y^2 of (x + y)^2.
A logarithm is an exponent?
A logarithm is quite the opposite of an exponential function. Whereas an exponential is y=ax , a log is logay=x For example, log39=2 because you raise 3 by the 2nd power to get 9. In other words, log39=2 because 32=9 Logarithms are present because they are a handy way to solve exponential equations, and because calculators use them to great advantage.
