Allen has been asked to replicate a scientific diagram in his notebook. The teacher has told him that variations in lengths of u

p to 2 centimeters are acceptable. If a test tube is 7 centimeters long in the original diagram, write an equation to help Allen find the maximum and minimum acceptable lengths of the test tube in his diagram. (Let x represent the length of the test tube in the new diagram.)

Which equation is equivalent to log^x36=2?
Dennis_Churaev [7]

The equation which is equivalent to \log _{x} 36=2 is x^{2}=36 or x = 6 (\log _{6} 36=2).

<u>Step-by-step explanation:</u>

Given Equation:

           \log _{x} 36=2

As we know, in terms of logarithmic rules, when b is raised to the power of y is equal x:

           b^{y}=a

Then, the base b logarithm of x is equal to y

           \log _{b}(x)=y

Now, use the logarithmic rule for the given equation by comparing with above equation. We get b = x, y = 2, and x = 36. Apply this in equation,

            b^{y}=a

            x^{2}=36

When taking out the squares on both sides, we get x = 6. Hence, the given equation can be written as \log _{6} 36=2
