What is the logarithmic form of the equation 4^x = 64 in base 10?

To convert the exponential equation 4x = 64 into its logarithmic form in base 10, we first need to understand the relationship between exponential and logarithmic expressions.

In general, the exponential equation ab = c can be rewritten in logarithmic form as loga(c) = b. Here, a is the base, b is the exponent, and c is the result of the exponential equation.

In our case, we can express 64 as a power of 4. Notice that:

64 = 43

Thus, we can rewrite the original equation as:

4x = 43

Since the bases are the same, we can set the exponents equal to each other:

x = 3

Now, to express this in logarithmic form, we can derive the equivalent form. Since we established that 4x = 64, we can say:

log4(64) = x

However, since the question specifically requests the logarithmic form in base 10, we need to use the change of base formula, which states:

loga(b) = logc(b) / logc(a)

Applying this formula with a = 4, b = 64, and c = 10, we can calculate:
log10(64) / log10(4) = x

So, in conclusion, the logarithmic form of the equation 4x = 64 in base 10 can be expressed as:

x = log10(64) / log10(4)

This gives you an equivalent way to represent the relationship established by the original exponential equation.
