You can put this solution on YOUR website!
2[8-(5)^3/25+] + 6} = 8 - 5^3/5^2 + 6 = 9
so
multiply by 2
2{2[8-(7-2)³÷25]+6} = 18
subtract 3
2{2[8-(7-2)³÷25]+6}-3 = 15

I'll do the first: 1. 2%282%288+-+%287+-+2%29%5E3%2F25%29+%2B+6%29+-+3
2%282%288+-+5%5E3%2F25%29+%2B+6%29+-+3
2%282%288+-+125%2F25%29+%2B+6%29+-+3
2[2(8 - 5) + 6] - 3
2[2(3) + 6] - 3
2(6 + 6) - 3
2(12) - 3
24 - 3 = highlight_green%2821%29
