Yo sup??

we can simply try option verification for this problem.

1 and 1≠5 therefore x=0 is not a solution.

when x=1 we get

√6-1≠5 therefore x=1 is not a solution.

when x=16 we get

9-4=5 therefore x=16 is a solution

Hence the correct answer is option C

from law of indices:

{x}^{a}  +  {x}^{b}  =  {x}^{(a + b)}

therefore:

= 21 \{ {w}^{(5 + 5)}  \} \\  \\  ={ \boxed{ 21 {w}^{10} }}
