Question

Evaluate the following when a= 1 ,b=3,and c =27 ( a) 6a^2+ 2bc-2c^1/3​

Answer 1

6a^2+ 2bc-2c^1/3 = 162

Explanation:

• a = 1
• b = 3
• c = 27

`\rm 6 {a}^(2) + 2bc - 2 {c}^{ (1)/(3) }`

`= 6 {(1)}^(2) + 2(3)(27) - 2( {27)}^{ (1)/(3) }`

`\rm = 6 + 162 - 2 ( \sqrt[3]{27} )`

`\rm = 168 - 2(3)`

`\rm = 168 - 6`

`\boxed{\rm = 162}`
