Q. Evaluate the logarithm.Round your answer to the nearest thousandth.2log3(521)≈□
Understand the expression: Understand the logarithm expression.We are given the expression 2log3(521) and need to evaluate it. The base of the logarithm is 3, and the argument is 521. The coefficient 2 in front of the logarithm indicates that we need to multiply the logarithm by 2 after evaluating it.
Apply logarithm properties: Apply the logarithm properties.We can use the property of logarithms that states loga(bn)=nloga(b). In this case, we can take the coefficient 2 and make it the exponent of the argument inside the logarithm:2log3(521)=log3((521)2).
Calculate square of fraction: Calculate the square of 521. We need to square the fraction521: (521)2=52212=27041. So, our expression becomes log3(27041).
Evaluate the logarithm: Evaluate the logarithm.To evaluate log3(27041), we need to find the power to which 3 must be raised to get 27041. Since 3 raised to any positive power will not result in a fraction smaller than 1, we know that the power must be negative. However, without a calculator, finding the exact value of this logarithm is not straightforward. We can use a calculator to find the value.
Use calculator for evaluation: Use a calculator to find the value of the logarithm.Using a calculator, we find:log3(27041)≈−6.287.
Round the answer: Round the answer to the nearest thousandth.Rounding −6.287 to the nearest thousandth gives us −6.287 since it is already at the thousandth place.
