5*[5+5*(5³-5 ²:5 ³)]+3*5²=5*[5+5*5³-5*5 ²:5 ³)]+3*5²=5*[5+5⁴-5³:5 ³)]+3*5²=5*[5+5⁴-1)]+3*5²=5²+5⁵-5+3*5²=5*(5+5⁴-1+3*5)=5*(5+625-1+15)=5*644=3220
5* [5+5*( 5^3 - 5^2 : 5^3 )] +3* 5^2 =
5* [ 5+ 5* (125 - 25 : 125 )] + 3* 25 =
5* [ 5+ 5 * (125-5) ] + 75 =
5* [5+ 5* 120 ] + 75 =
5* [ 5+ 600] + 75 =
5* 605 + 75 = 3025 + 75 = 3100
