-5^2\left(-5^-\right)\cdot \:5\left(-5^0\right)\left(-5^7\right)

=-\left(-5^-\right)\cdot \:5^{2+1}\left(-5^0\right)\left(-5^7\right)

=-\left(-5^-\right)\cdot \:5^3\left(-5^0\right)\left(-5^7\right)

=-5^3\left(-1\right)\left(-5^-\right)\left(-5^7\right)

=5^-\cdot \:5^3\cdot \:1\cdot \:5^7

=1\cdot \:5^{-+3+7}

=5^{-+3+7}

=5^{10}

=9765625
