Question

If g = `t^(2/3) + 4t^(-1/2)`, what is the value of g when t = 64?

Options

  • `31/2`

  • `33/2`

  • 16

  • `257/16`

MCQ

Solution

`bb(33/2)`

Explanation:

g = `t^(2/3) + 4t^(-1/2)`

= `(64)^(2/3) + 4(64)^(-1/2)`

= `[(64)^(1/3)]^3 + 4 (1/64)^(1/2)`

= `4^2 + 4(1/8)`

= `16 + 1/2 = 38/2`
