What is the solution to 2log5x = log54?
Answer: 2
6. Which equation is equivalent to log5x3 - logx2 = 2?
Answer: 10^log5^3/x^2=10^2
Solve: log5x3 - logx2 = 2
Answer: 20
7. What is the solution to ln (x2 - 16) = 0?
Answer: x=+-(17)
8. Solve: ln 2x + ln 2 = 0
Answer: ¼
Solve: e^ 2x+5 = 4
Answer: x=(In4) - 5/2
9. Consider the equation log(3x - 1) = log2(8). Explain why 3x - 1 is not equal to Describe the steps you would take to solve the equation, and state what 3x - 1 is equal to.
Answer: The bases are not the same, so you cannot set 3x - 1 equal to 8.You can evaluate the logarithm on the right side of the equation to get .You can use the definition of a logarithm to write 3x - 1 = 1000.
10. An initial investment of $100 is now valued at $150. The annual interest rate is 5%, compounded continuously. The equation 100e^0.05t = 150 represents the situation, where t is the number of years the money has been invested. About how long has the money been invested? Use your calculator and round to the nearest whole number.
Answer: 8
