[tex]0,5^6 \times 7 \times 2^6 = (0,5 \times2)^6 \times 7 = 1^6 \times 7 = 7\\ \\ 2^7 \times 3^3 \times 5^6 = 4^6 \times 3^3 \times 5^3 \times 5^3 \\ = 2 \times 2^3 \times 2^3 \times 4^3 \times 3^3 \times 5^3 \times 5^3 \\ = 2 \times (2 \times 2 \times 3 \times 5 \times 5)^3 \\ = 2 \times (10 \times 10 \times 3)^3\\ = 2 \times 3^3 \times 100^3\\ = 2 \times 27 \times 1000000\\ = 54000000[/tex]
