Question

Me ajudem por favor e pra amanhã cedo

Answer 1

$100\times2^{\frac{t}{46}}=1000\\\\2^{\frac{t}{46}}=\frac{1000}{100}\\\\log\,2^{\frac{t}{46}}=log\,10\\\\\frac{t}{46}log\,2=log\,10\\\\\frac{t}{46}\times0,3=1\\\\\frac{t}{46}=\frac{1}{0,3}\\\\t = 46\times \frac{10}{3}\\\\t=\frac{460}{3}\approx153,33\,segundos$
