WebUsing a calculator, we can use common and natural logarithms to solve equations of the form a x = b, especially when b cannot be expressed as a n. Example: Solve the equations a) 6 x + 2 = 21 b) e 2x = 9 Solution: a) 6 x + 2 = 21 log 6 x + 2 = log 21 (x + 2) log 6 = log 21 b) e 3x = 9 ln e 3x = ln 9 3x ln e = ln 9 3x = ln 9 Example: WebThe power rule for logarithms can be used to simplify the logarithm of a power by rewriting it as the product of the exponent times the logarithm of the base. log b (M n) = n log b M log b (M n) = n log b M.

WebUse the Division Rule of Exponent by copying the common base of e e and subtracting the top by the bottom exponent. Now isolate the exponential expression by adding both sides by 7 7, followed by dividing the entire equation by 2 2. Take the logarithm of both sides. Use \color {red}ln ln because we have a base of e e. WebAtsbhayohans 7 years ago simple just follow these steps! 1)log2 (2x)-log2 (x^3)=5 write in the form that is logbX-logbY=logbX/Y; then this will become log2 (2x/ (x^3) )=5 2)log2 (2/x^2)=5 3) 2^5=2/x^2 => 32=2/x^2 = 32x^2=2 = x^2=1/16 = x=1/4 .....final answer; 10Q ( 5 votes) Show more... Cooper Young 11 years ago Webto the natural exponential we saw above. A log with base e is called a natural log and is written as follows: log e a = lna. These bases are simply special cases of the logs we’ve already be studying, so all of the above rules apply. Example Simplify lne13. Example Simplify e2lnˇ.
