These problems are from the NYS math b regents our teacher assigned for us to do. Please help on these thanks!

T=2(pi)(squareroot)l/g where g is 32.( sorry for not knowing how to make pis and square roots). How is this equation expressed in log form?

1. logT= log2 + logpi + log(sqroot) l-32

2. logT= log 2 + logpi + 1/2logl-1/2log32

3. logT= log 2 + log pi + 1/2log l - 16

4. log T= 2 + log pi + 1/2log l - 16

Which equation has the complex number 4-3i as a root

1. x^2 +6x-25= 0

2. x^2-6x+25=0

3. x^2 + 8x - 25=0

4. x^2-8x+ 25= 0

1. 1

2. 2

3. 3

4. 4
