professor190 [17]

Answer: The answer is (c) ln 4768 = 5x.

Step-by-step explanation:  The given equation is

e^{5x}=4768.

We are to find the logarithmic form of the above equation.

We will be using the following properties of logarithm :

(i)~\ln a^b=b\ln a,\\\\(ii)~\ln e=1.

The solution is as follows:

e^{5x}=4768\\\\\Rightarrow \ln{e^{5x}}=\ln 4768\\\\\Rightarrow 5x\ln e=\ln 4768\\\\\Rightarrow 5x\times 1=\ln4768\\\\\Rightarrow 5x=4768.

Thus, the correct option is (c).

sveticcg [70]

Answer:

36/45 and 35/45

Step-by-step explanation:

5 and 9's least common denominator is 45 and to get to that you need to multiply both top and bottom of how to get to 45. How I got to 45 the easiest way is to keep multiplying both numbers until the reach the same product. In this case for 4/5, you multiply it by 9 for top and bottom. And for 7/9, it would be multiplying by 5 for top and bottom which will get you both of the answers. Hopefully this answers your question.
