Find the Domain 100^2+100^2=100^x
Problem
Solution
Identify the type of equation. This is an exponential equation where we are looking for the domain of the variable
x that satisfies the equality.Simplify the left side of the equation by combining like terms.
Rewrite the equation using the simplified left side.
Determine the domain. In an exponential equation of the form
ab=cx wherea>0 the variablex can be any real number for the expression100 to be defined.Analyze the specific solution for
x to ensure it exists. By taking the logarithm of both sides, we findx=(log_100)(2⋅100) which is a well-defined real number.Conclude that since there are no square roots of negative numbers, denominators that could be zero, or logarithms of non-positive numbers involving the variable
x in the original expression, the domain is all real numbers.
