To simplify the expression \( 4^{13} \div 3 - 5 \), we can follow these steps:
-
Calculate \( 4^{13} \).
- First, notice that \( 4 = 2^2 \), so \( 4^{13} = (2^2)^{13} = 2^{26} \).
-
Substitute this back into the expression: \[ \frac{2^{26}}{3} - 5 \]
-
Since \( 2^{26} \) is quite a large number, it's helpful to evaluate \( 2^{26} \) directly: \[ 2^{26} = 67108864 \]
-
Now evaluate \( \frac{67108864}{3} \): \[ 67108864 \div 3 \approx 22369621.33 \]
-
Now subtract 5 from this: \[ 22369621.33 - 5 = 22369616.33 \]
So, the final simplified result of the expression \( 4^{13} \div 3 - 5 \) is approximately: \[ \boxed{22369616.33} \]
