The Deep Dive
To solve \( (20: 5)^{2}-\sqrt{64}+\sqrt[3]{8} \), let's break it down step by step. First, \( 20: 5 \) equals \( 4 \). So, we have: \( (4)^{2} = 16 \). Next, we calculate \( \sqrt{64} \), which equals \( 8 \). Finally, \( \sqrt[3]{8} \) equals \( 2 \) since \( 2^3 = 8 \). Putting it all together: \[ 16 - 8 + 2 = 10. \] Thus, the final answer is \( 10 \).
