Question

2. Find the value of
`5\sqrt[3]{1728} + 100 \sqrt[4]{81} - (6√(10) )x^(2)`

(a) 1 (b) 0 (c) 8 (d) 10

Answer 1

(b) 0

Explanation:

Assuming a typo in the last term:

5 (1728)^(1/3) + 100(81)^(1/4) - ( 6(10)^(1/2) )^2

=5(12) + 100(3) -36(10)

=60+300-360

=0

Answer 2

`\boxed{\sf (b) \ 0}`

Explanation:

`\sf 5\sqrt[3]{1728} +100\sqrt[4]{81} -(6√(10) )^2`

`\sf Evaluate.`

`\sf 5(12)+100(3) -((6)^2 (√(10))^2)`

`\sf 60+300 -(36(10))`

`\sf 360-360`

`\sf 0`
