Q. Consider the equation−16×106x=−80. Solve the equation for x. Express the solution as a logarithm in base−10.x=Approximate the value of x. Round your answer to the nearest thousandth.x≈
Identify Equation: Identify the equation that needs to be solved.The equation given is −16×106x=−80.
Isolate Exponential Term: Isolate the exponential term.To isolate the exponential term, divide both sides of the equation by \(-16").\(-16\cdot10^{(6x)} / −16 = −80 / −16")\(10^{(6x)} = 5")
Apply Logarithm: Apply the logarithm to both sides of the equation.To solve for x, take the logarithm of both sides of the equation. We will use the base-10 logarithm since the exponential base is 10.log(106x)=log(5)
Use Power Property: Use the power property of logarithms.The power property of logarithms states that logb(mn)=n⋅logb(m). Apply this property to the left side of the equation.6x⋅log(10)=log(5)
Simplify Equation: Simplify the left side of the equation.Since log(10) is equal to 1, the equation simplifies to:6x=log(5)
Solve for x: Solve for x.Divide both sides of the equation by 6 to solve for x.x=6log(5)
Approximate Value: Approximate the value of x. Use a calculator to find the value of log(5) and then divide by 6. x≈log(5)/6x≈0.69897/6x≈0.116495 Round the answer to the nearest thousandth. x≈0.116
