0 = 0.1t^4 - 3.2t^1.5
multiply by 10 to get
t^4 - 32t^1.5 = 0
simplify
t^4 = 32t^1.5
( t^4 )² = ( 32t^1.5 )²
t⁸ = 1024t³
t⁸ - 1024t³ = 0
t³ ( t⁵ - 1024 ) = 0
t = 0
t⁵ = 1024 ====> t = 4
t = 0 and t = 4

Did you try an online solver?
0 = t^1.5 * (0.1t^2.5 - 3.2)
t = 0 or t = 32^(1/2.5) = 32^(2/5) = 4
