To find out which expression simplifies to \( 87 - \sqrt{3} \), we can analyze each of the provided options one by one.
1. **Option 1: \( -67 - \sqrt{3} - 27 - \sqrt{3} \)**
\[
= -67 - 27 - \sqrt{3} - \sqrt{3} = -94 - 2\sqrt{3} \quad (\text{not } 87 - \sqrt{3})
\]
2. **Option 2: \( -6\sqrt[3]{7} - 2\sqrt[3]{7} \)**
\[
= -8\sqrt[3]{7} \quad (\text{clearly not } 87 - \sqrt{3})
\]
3. **Option 3: \( 36 - \sqrt{3} + 51 - \sqrt{3} \)**
\[
= (36 + 51) - (1\sqrt{3} + 1\sqrt{3}) = 87 - 2\sqrt{3} \quad (\text{not } 87 - \sqrt{3})
\]
4. **Option 4: \( 3\sqrt[3]{6} + 5\sqrt[3]{1} \)**
\[
= 3\sqrt[3]{6} + 5 \quad (\text{not } 87 - \sqrt{3})
\]
5. **Option 5: \( 256 - \sqrt{3} - 47 - \sqrt{3} \)**
\[
= (256 - 47) - (1\sqrt{3} + 1\sqrt{3}) = 209 - 2\sqrt{3} \quad (\text{not } 87 - \sqrt{3})
\]
6. **Option 6: \( 2\sqrt[3]{56} - 4\sqrt[3]{7} \)**
\[
= 2\sqrt[3]{8 \cdot 7} - 4\sqrt[3]{7} = 4\sqrt[3]{7} - 4\sqrt[3]{7} = 0 \quad (\text{not } 87 - \sqrt{3})
\]
7. **Option 7: \( 56 - \sqrt{3} + 67 - \sqrt{3} \)**
\[
= (56 + 67) - (1\sqrt{3} + 1\sqrt{3}) = 123 - 2\sqrt{3} \quad (\text{not } 87 - \sqrt{3})
\]
None of the expressions provided simplifies to \( 87 - \sqrt{3} \). Please double-check the expressions given or provide additional context.
