Question

 Calculati:  3 la 100:[ 3 la 40ori 3 la 58-(3 la 10 ori 3 la 15 ) la 5 :3 la 27+(4 la 57 ori 4 la 56 - 1 la 2007)la 97]ori 7

Answer 1

3^100:[3^40 × 3^58 - (3^10 × 3^15)^5 : 3^27 +(4^57 × 4^56 - 1^2007)^97]×7=3^100:[3^98 - 3^125 : 3^27 +(4^113-1)^97]×7=3^100:[3^98-3^98+(4^113-1)^97]×7=3^100:[(4^113-1)^97]×7=(3^100×7)/[(4^113-1)^97]
