Question

Please help quickly I really don’t understand this question and i’m freaking out.

Answer 1

`(4 √(3x) )/(9)`

Explanation:

`\frac{4 \sqrt{ {21x}^(2) } }{3 √(63x) }`

`\frac{4 \sqrt{ \frac{21 {x}^(2) }{63x} } }{3}`

`\frac{4 \sqrt{ (x)/(3) } }{3}`

`\frac{4 \sqrt{ (x * 3)/(3) } }{3}`

`((4 √(3x) )/(3) )/(3)`

`(4 √(3x) )/(3) * (1)/(3)`

`(4 √(3x) )/(9)`

Hope it is helpful...
