To simplify the expression \((734)^5\), you would apply the Power Rule of Exponents, which states that \((a^m)^n = a^{m \cdot n}\). In this case, you do not have an exponent raised to another exponent but directly have the base raised to a power.
\((734)^5\) is already in its simplest form as a single exponentiation. However, if you want to express this in expanded form, it means multiplying 734 by itself five times:
\[ (734)^5 = 734 \times 734 \times 734 \times 734 \times 734 \]
If you are looking for a numerical value, \(734^5\) would require calculation. Here’s the simplified expression without calculating the numerical value further:
\[ 734^5 \]
So, no further simplification can be done, and the expression is best left like that unless you need the numerical result.
