Q. Solve. Round your answer to the nearest thousandth.8=7xx=____
Apply Logarithms:8=7xApply logarithms to both sides of the equation to solve for x.Take the natural logarithm (ln) of both sides.ln(8)=ln(7x)
Use Power Property:ln(8)=ln(7x)Use the power property of logarithms to bring the exponent x in front of the ln(7).Power Property: ln(Mn)=n⋅ln(M)ln(8)=x⋅ln(7)
Isolate x:ln(8)=x⋅ln(7)Isolate x by dividing both sides of the equation by ln(7).x=ln(7)ln(8)
Calculate x: Calculate the value of x using a calculator.x=ln(7)ln(8)x≈1.9459101491.079181246x≈0.554517Round the answer to the nearest thousandth.x≈0.555
