To simplify the expression \((7^3)^4\) to the power of 5 using the power rule of exponents, which states that \((a^m)^n = a^{m \cdot n}\), you can follow these steps:
- Start with the expression: \((7^3)^4\)
- Apply the power rule: \((7^3)^4 = 7^{3 \cdot 4} = 7^{12}\)
Now you need to raise \(7^{12}\) to the power of 5:
- Now take \( (7^{12})^5 \): \((7^{12})^5 = 7^{12 \cdot 5} = 7^{60}\)
So, the simplified expression is:
\[ 7^{60} \]
