Isolate exponential term: Isolate the exponential term.To solve for t, we first need to isolate the term with the exponent. We do this by dividing both sides of the equation by 11.11⋅105t=20105t=1120
Apply logarithm to both sides: Apply the logarithm to both sides of the equation.To solve for the exponent, we apply the logarithm to both sides of the equation. We will use the common logarithm (base 10).log(105t)=log(1120)
Use property of logarithms: Use the property of logarithms to bring down the exponent.The property of logarithms that we use here is log(bx)=x⋅log(b). We apply this property to the left side of the equation.5t⋅log(10)=log(1120)
Simplify left side: Simplify the left side of the equation.Since log(10) is equal to 1, the equation simplifies to:5t=log(1120)
Solve for t: Solve for t.To solve for t, we divide both sides of the equation by 5.t=5log(1120)
Approximate value of t: Approximate the value of t.Using a calculator, we can find the approximate value of t by evaluating the logarithm and dividing by 5.t≈5log(1120)t≈5log(1.81818181818)t≈50.2596373105t≈0.0519274621Rounded to the nearest thousandth, t≈0.052
