Q. Solve for x, rounding to the nearest hundredth.7⋅34x=1Answer:
Isolate exponential term: First, we need to isolate the exponential term on one side of the equation. Since we are given 7⋅34x=1, we can divide both sides by 7 to get 34x on its own.Calculation: 34x=71
Solve for x: Next, we need to solve for x in the exponential equation. To do this, we can take the natural logarithm (ln) of both sides of the equation to remove the base 3 exponent.Calculation: ln(3(4x))=ln(71)
Simplify using logarithms: Using the property of logarithms that ln(ab)=b⋅ln(a), we can simplify the left side of the equation.Calculation: (4x)⋅ln(3)=ln(71)
Multiply by ln(3)4: Now, we solve for x by multiplying both sides of the equation by ln(3)4.Calculation: x=ln(3)4⋅ln(71)
Calculate numerical value of x: We can now use a calculator to find the numerical value of x.Calculation: x≈(4∗ln(1/7))/ln(3)≈(4∗(−1.9459101490553135))/1.0986122886681098≈−7.087712930
Round to nearest hundredth: Finally, we round the value of x to the nearest hundredth.Calculation: x≈−7.09
