Question

Please answer all six questions! : )

Answer 1

`18-(\sqrt[3]{27})^3=18-27=-9`


`\left(\sqrt[3]{-\frac18}\right)^3+3\frac34=-\frac18+\frac{15}4=\frac{29}8=3\frac58`


`5\sqrt[3]{729}-24=5*9-24=21`


`\frac14-2\sqrt[3]{-\frac1{216}}=\frac14-2*\left(-\frac16\right)=\frac7{12}`


`54+\sqrt[3]{-4096}=54-16=38`


`4\sqrt[3]{8000}-6=4*20-6=74`
