Identify Given Equation and Goal: Identify the given equation and the goal.We are given that 3a=534, and we need to find the value of a.
Rewrite Square Root as Exponent: Rewrite the square root of 34 as an exponent.The square root of a number is the same as raising that number to the power of 1/2. So, 34 is the same as (34)1/2.
Apply Power of Power Rule: Apply the power of a power rule.According to the power of a power rule, (xm)n=x(m∗n). Therefore, (34)1/2=3(4∗(1/2)).
Simplify the Exponent: Simplify the exponent. 34∗(1/2) simplifies to 32 because 4∗(1/2) equals 2.
Substitute Simplified Exponent: Substitute the simplified exponent back into the equation.Now we have 3a=5×32.
Divide to Isolate 3a: Divide both sides of the equation by 32 to isolate 3a. Doing this, we get (3a)/(32)=5.
Apply Quotient of Powers Rule: Apply the quotient of powers rule.According to the quotient of powers rule, am/an=am−n. Therefore, (3a)/(32)=3a−2.
Set Expression Equal to 5: Set the expression equal to 5. Now we have 3(a−2)=5.
Solve for a with Logarithm: Solve for a by taking the logarithm of both sides.To solve for a, we can take the logarithm with base 3 of both sides, which gives us a−2=log3(5).
Isolate a by Adding 2: Isolate a by adding 2 to both sides.Adding 2 to both sides gives us a=log3(5)+2.
Calculate log3(5): Calculate the value of log3(5). Using a calculator or logarithm properties, we find that log3(5) is approximately 1.465 (rounded to three decimal places).
Add 2 to log3(5): Add 2 to the approximate value of log3(5). Adding 2 to 1.465 gives us a≈1.465+2.
Calculate Final Approximate Value: Calculate the final approximate value of a.a≈1.465+2≈3.465.
