Question 193718
Assuming  the  problem  is:
,
5 * sqrt ( 1024 x^4y^22)
5*  sqrt(1024) * sqrt(x^4) * sqrt (y^22)
5 * 32 * x^2 * y^11
160 x^2 y^11


check
let  x=3,,,y=4,,,,arbitrarily
original  is  5*sqrt ( 1024*3^4*4^22) = 5* sqrt (1.459 x 10^18) =5*1.2 x10^9=6x10^9
answer is  160 *x^2*y^11=160*3^2*4^11=6 x10^9,,,,,,therefore  matches
