[tex]5 \times {5}^{3} \times {5}^{5} \times {5}^{7} \div { ({( - 5)}^{3} })^{4} - {( - 2)}^{3} \times {( - 3)}^{2} \times {( - 5)}^{4} = \\ \\ {5}^{1 + 3 + 5 + 7} \div {5}^{3 \times 4} + {2}^{3} \times {( - 3)}^{2} \times {( - 5)}^{4} = \\ \\ {5}^{16} \div {5}^{12} + (8 \times 9 \times 625) = \\ \\ {5}^{4} + 45000 = \\ \\ 625 + 45000 = 45625[/tex]
Succes!
