Question

how do i do this?

Answer 1

logs help

Answer 2

?

Answer 3

log(a^x) = x log(a)

after that its just simple addition and multilication to play with

Answer 4

oh u do bases the same

Answer 5

4 * 5 = 20

5*2 t = 10t

5*4 =20

4*4 + 4
16 t + 16

10 t = 16 t + 16
-16t - 16 t
--------------------
-6 = 16

t = -8/3

Answer 6

how do i solve the 2 one?

Answer 7

??? anyone???

Answer 8

2t log(4) = (4t+4) log(5)

t log(4) = 2t log(5) +2(log(5))

t log(4) -2t log(5)= 2 log(5)

t (log(4) -2log(5))= 2log(5)

t = 2 log(5)/(log(4) - 2log(5))

t = 2 log(5)/(2log(2) - 2log(5))

t = log(5)/(log(2) - log(5))
