Given the exponential function:


10^(2a+3)=10^(a-4)

Let's evaluate the given exponential function.

Since the base of both sides are the same, the expressions are equal if the exponents are equal.

Remove the bases and equate the exponents:


2a+3=a-4

Subtract 3 from both sides:


\begin{gathered} 2a+3-3=a-4-3 \\ \\ 2a=a-7 \end{gathered}

Subtract a from both sides:


\begin{gathered} 2a-a=a-a-7 \\ \\ a=-7 \end{gathered}

ANSWER:

a = -7
