Tugas Kelompok ke-2 Week 5, Sesi 7 1. Tentukan nilai x dari : a. 5 2 x = 11 2 x = 5 11 2 log 5 11 = x x = - 1,1375 b. x 3 = 6 x = 3 6 x = 1,81712 c. log 3 x = 4 x = 3 4 x = 81 d. log 5 x = log 10 x . log 5 = log 10 x = 1 log5 x = 1,431 e. ( 25 ) 2 x + 4 = 5 2 x 4 (5) 2(2 x + 4) = 5 2x - 4 4 x + 8 = 2 x – 4 2 x = -12 x = -6 2. Intan memiliki uang sebesar Rp. 5.000.000,- yang akan disimpan pada sebuah Bank selama tiga tahun.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
