(d)solve gives not-calculated coefficients

When I use "solve" to solve a system of equations, matlab always gives results like x=56980860677234865024000/16845271251976007028871 but I can use "double(x)" to fix it.

However, this time I was trying to use "dsolve" to solve a system of differential equations, the result is like (56980860677234865024000*t)/16845271251976007028871-exp((5*t*(41585177577736871350142061444646828960608054585^(1/2)... so how to deal with it?

Thanks a lot
