Question

512000=1000x2^t, como faço pra encontrar o t ?

Answer 1

$512000 = 1000 \times {2}^{t}$
2^t= 512000÷1000
2^t= 512
t= 512÷2
t= 256

Answer 2

                512000 = 1000 x 2^t
                512 = 1 x 2^t
                   2⁹ = 2^t   <-- bases iguais , iguala os expoentes
                    9 = t
