To solve the exponential equation 61−T=53T+1, we can take the logarithm of both sides. We can use any base for the logarithm, but it's common to use the natural logarithm (base e), denoted as ln. Taking the natural logarithm of both sides gives us:
ln(61−T)=ln(53T+1) Using the logarithm power rule ln(ab)=b⋅ln(a), we have: (1−T)⋅ln(6)=(3T+1)⋅ln(5) Now, we distribute the ln(6) and ln(5) on each side: ln(6)−T⋅ln(6)=3T⋅ln(5)+ln(5) Next, we want to isolate T terms on one side of the equation and constant terms on the other side. So, we add T⋅ln(6) to both sides and subtract ln(5) from both sides: ln(6)−ln(5)=3T⋅ln(5)+T⋅ln(6) Now, we factor out T from the right side: ln(6)−ln(5)=T(3ln(5)+ln(6)) Finally, we divide both sides by (3ln(5)+ln(6)) to solve for T: T=3ln(5)+ln(6)ln(6)−ln(5) We can simplify the expression using logarithm properties. Specifically, a⋅ln(b)=ln(ba). T=ln(53)+ln(6)ln(6)−ln(5) T=ln(125)+ln(6)ln(6)−ln(5) T=ln(125⋅6)ln(6/5) T=ln(750)ln(6/5) We can also approximate the value using a calculator:
ln(6)≈1.791759 ln(5)≈1.609438 3ln(5)≈4.828314 T≈4.828314+1.7917591.791759−1.609438=6.6200730.182321≈0.02754
