PLEASE HELP I DONT KNOW HOW TO SOLVE THIS

sqrt3(-8)+sqrt(-3^2)-sqrt4((-25)^4)

sqrt3(-8)+sqrt(-3^2)-sqrt4((-25)^4)

I have a feeling that this is supposed to be

³√ (-8)   + √ (-3)^2  - ⁴√ (-25)^4       if so.....we have

-2  + √9  - ⁴√ ( -1 * 25)^4     =

-2 + 3  - ⁴√ [ (-1)^4  * (25)^4 ]  = 

1  -  ⁴√ [25 ^4 ]  =

1 - 25  =

-24
