Full solution

Q. Solve for x x , rounding to the nearest hundredth.\newline73x4=1 7 \cdot 3^{\frac{x}{4}}=1 \newlineAnswer:
  1. Isolate exponential term: First, we need to isolate the exponential term on one side of the equation. Since we are given 73x4=17\cdot3^{\frac{x}{4}}=1, we can divide both sides by 77 to get 3x43^{\frac{x}{4}} on its own.\newlineCalculation: 3x4=173^{\frac{x}{4}} = \frac{1}{7}
  2. Solve for xx: Next, we need to solve for xx in the exponential equation. To do this, we can take the natural logarithm (ln\ln) of both sides of the equation to remove the base 33 exponent.\newlineCalculation: ln(3(x4))=ln(17)\ln(3^{(\frac{x}{4})}) = \ln(\frac{1}{7})
  3. Simplify using logarithms: Using the property of logarithms that ln(ab)=bln(a)\ln(a^b) = b\cdot\ln(a), we can simplify the left side of the equation.\newlineCalculation: (x4)ln(3)=ln(17)(\frac{x}{4})\cdot\ln(3) = \ln(\frac{1}{7})
  4. Multiply by 4ln(3)\frac{4}{\ln(3)}: Now, we solve for xx by multiplying both sides of the equation by 4ln(3)\frac{4}{\ln(3)}.\newlineCalculation: x=4ln(17)ln(3)x = \frac{4\cdot\ln(\frac{1}{7})}{\ln(3)}
  5. Calculate numerical value of x: We can now use a calculator to find the numerical value of xx.\newlineCalculation: x(4ln(1/7))/ln(3)(4(1.9459101490553135))/1.09861228866810987.087712930x \approx (4*\ln(1/7))/\ln(3) \approx (4*(-1.9459101490553135))/1.0986122886681098 \approx -7.087712930
  6. Round to nearest hundredth: Finally, we round the value of xx to the nearest hundredth.\newlineCalculation: x7.09x \approx -7.09
