Evaluate 4√256 + 3√216 - 6√64
4√256 + 3√216 - 6√64 = [4(√2*2*2*2*2*2*2*2)] + [3(√2*2*2*3*3*3)] - [6(√2*2*2*2*2*2)]
= (4*2*2*2*2) + (3*2*3*√6) - (6*2*2*2)
= 64 + 81√6 - 48
= 16 + 81√6
The equation above is the simplified form of your question. For evaluation you need to find √6.
So, √6 ≈ 2.45
Then, 16 + 81√6 = 16 +(81*2.45)
= 16 + 198.45
= 214.45
Hope my answer helps
