Can someone help me with these questions 1-7 thanks

Answer:
1)3
2)2
3) -4
4) -5/6
5)-2
6)26
7)10 inch
Step-by-step explanation:
1)
[tex] \sqrt[3]{27} = \sqrt[3]{ {3}^{3} } = 3[/tex]
2)
[tex] \sqrt[3]{8} = \sqrt[3]{ {2}^{3} } = 2[/tex]
3)
-64 is equals to (-4)^3, so it's cube root will be -4
4)-125/216 = {(-5)/(6)}^3 so cube root will be -5/6
5) cube of cube root of 12 will be 12
so the equn becom 10-12= -2
6)512= 8^3, so its cube root will be 8
now equn becomes 2×8+10=26
7( volume of cube = (side)^3=1000=(10)^3
so side will be 10
