Full solution

Q. if 3a=5343^a=5\sqrt{3^4},what is the value of aa?
  1. Identify Given Equation and Goal: Identify the given equation and the goal.\newlineWe are given that 3a=5343^a = 5\sqrt{3^4}, and we need to find the value of aa.
  2. Rewrite Square Root as Exponent: Rewrite the square root of 343^4 as an exponent.\newlineThe square root of a number is the same as raising that number to the power of 1/21/2. So, 34\sqrt{3^4} is the same as (34)1/2(3^4)^{1/2}.
  3. Apply Power of Power Rule: Apply the power of a power rule.\newlineAccording to the power of a power rule, (xm)n=x(mn)(x^m)^n = x^{(m*n)}. Therefore, (34)1/2=3(4(1/2))(3^4)^{1/2} = 3^{(4*(1/2))}.
  4. Simplify the Exponent: Simplify the exponent. 34(1/2)3^{4*(1/2)} simplifies to 323^2 because 4(1/2)4*(1/2) equals 22.
  5. Substitute Simplified Exponent: Substitute the simplified exponent back into the equation.\newlineNow we have 3a=5×323^a = 5 \times 3^2.
  6. Divide to Isolate 3a3^a: Divide both sides of the equation by 323^2 to isolate 3a3^a. Doing this, we get (3a)/(32)=5(3^a) / (3^2) = 5.
  7. Apply Quotient of Powers Rule: Apply the quotient of powers rule.\newlineAccording to the quotient of powers rule, am/an=amna^m / a^n = a^{m-n}. Therefore, (3a)/(32)=3a2(3^a) / (3^2) = 3^{a-2}.
  8. Set Expression Equal to 55: Set the expression equal to 55. Now we have 3(a2)=53^{(a-2)} = 5.
  9. Solve for aa with Logarithm: Solve for aa by taking the logarithm of both sides.\newlineTo solve for aa, we can take the logarithm with base 33 of both sides, which gives us a2=log3(5)a - 2 = \log_3(5).
  10. Isolate aa by Adding 22: Isolate aa by adding 22 to both sides.\newlineAdding 22 to both sides gives us a=log3(5)+2a = \log_3(5) + 2.
  11. Calculate log3(5)\log_3(5): Calculate the value of log3(5)\log_3(5). Using a calculator or logarithm properties, we find that log3(5)\log_3(5) is approximately 1.4651.465 (rounded to three decimal places).
  12. Add 22 to log3(5)\log_3(5): Add 22 to the approximate value of log3(5)\log_3(5). Adding 22 to 1.4651.465 gives us a1.465+2a \approx 1.465 + 2.
  13. Calculate Final Approximate Value: Calculate the final approximate value of aa.a1.465+23.465a \approx 1.465 + 2 \approx 3.465.
