Question

What’s the answer to this?

Answer 1

The answer is 6/(5x^10)

Answer 2

Root ((72x ^ 16) / (50x ^ 36))
 The first thing we must do in this case is to rewrite the expression:
 Root ((36x ^ 16) / (25x ^ 36))
 (6/5) * Root ((x ^ 16) / (x ^ 36))
 Then, for power properties we have:
 (6/5) * Root ((x ^ (16-36))
 (6/5) * Root ((x ^ (- 20))
 (6/5) * Root (1 / (x ^ 20))
 We rewrite the expression again:
 (6/5) * ((1) ^ (1/2) / (x ^ 20) ^ (1/2))
 (6/5) * (1 / (x ^ 10))
 (6 / (5 * x ^ 10))
 Answer: 
 (6 / (5 * x ^ 10))
