Simplifying the Equation for x

In mathematics, equations involving logarithms can be complex and challenging to solve. However, with the right approach and techniques, we can simplify these equations and find their solutions. In this article, we will focus on simplifying the equation for x, which involves logarithmic functions.

Understanding the Equation

The given equation is:

x=log⁡10log⁡5+12x = \frac{\frac{\log 10}{\log 5} + 1}{2}

To simplify this equation, we need to understand the properties of logarithms and how they can be manipulated. The equation involves the logarithm of 10 and 5, which are both base-10 logarithms. We can use the change-of-base formula to rewrite the equation in a more manageable form.

Change-of-Base Formula

The change-of-base formula states that:

log⁡ba=log⁡calog⁡cb\log_b a = \frac{\log_c a}{\log_c b}

where aa, bb, and cc are positive real numbers. We can use this formula to rewrite the equation in terms of a common base.

Rewriting the Equation

Using the change-of-base formula, we can rewrite the equation as:

x=log⁡10log⁡5+12=log⁡10log⁡5+log⁡5log⁡52x = \frac{\frac{\log 10}{\log 5} + 1}{2} = \frac{\frac{\log 10}{\log 5} + \frac{\log 5}{\log 5}}{2}

Simplifying the equation further, we get:

x=log⁡10+log⁡5log⁡52=log⁡10+log⁡52log⁡5x = \frac{\frac{\log 10 + \log 5}{\log 5}}{2} = \frac{\log 10 + \log 5}{2 \log 5}

Using Logarithmic Properties

We can use the property of logarithms that states:

log⁡a+log⁡b=log⁡(ab)\log a + \log b = \log (ab)

to simplify the equation further. Applying this property, we get:

x=log⁡(10⋅5)2log⁡5=log⁡502log⁡5x = \frac{\log (10 \cdot 5)}{2 \log 5} = \frac{\log 50}{2 \log 5}

Simplifying the Equation

We can simplify the equation further by using the property of logarithms that states:

log⁡ab=blog⁡a\log a^b = b \log a

Applying this property, we get:

x=log⁡502log⁡5=log⁡522log⁡5=2log⁡52log⁡5x = \frac{\log 50}{2 \log 5} = \frac{\log 5^2}{2 \log 5} = \frac{2 \log 5}{2 \log 5}

Final Simplification

Simplifying the equation further, we get:

x=2log⁡52log⁡5=1x = \frac{2 \log 5}{2 \log 5} = 1

Therefore, the final simplified equation for x is:

x=1x = 1

Conclusion

In this article, we simplified the equation for x, which involved logarithmic functions. We used the change-of-base formula, logarithmic properties, and simplification techniques to arrive at the final solution. The simplified equation for x is x = 1.
