Math HW

Show answer and also Needs to show each step in solving each problem is required

12.1Round to three deciamal places
1. 2^3.4=
2. 3^sqrt5=11

12.2

1. 4= 1og2 16=
3. 2= 1og3 x=

12.3

1. log5 (7*3)=
3. log7 (7x)=

12.4 Solve each expnential equation by expressing each side as power of the same base and then equatiing xponents

1. 2^x =64
3.5^x =125

12.5

The exponential models describe the population of the indicated country, A, in miilions, t years after 2006. Use these models to solve.
India A= 1095.4e^0.014t
Iraq A = 26.83^0.027t
Japan A=127.5e^0.001t
Russia A = 1492e^-0.004t

1. What was the population of Japan in 2006( Show each steps in solve this problem)

3.Which country has the greates growth rate? By what perentage is the population of that country increasing each year? (Show each steps in solving this problem)

2.Determine equation is true or false explaing why and if false what changes need to be made to make true statement

78, In(8x^3) = 3 In(2x)

Solve each Logarithmic equation Be sure to reject any value of x that is not in domain of the original logarithmic expressions give exact ansewer where neccessary use clalcualtor obtain deciamal approx correct two deciamal places for solution

log6(x+5) + log6 x=2
