`6. (-4^2) .(-10^2) + (-5)^2`
`=6. 16 . 100 + 25`
`= 96.100+25`
`=9600+25`
`=9625`
\(6\cdot\left(-4^2\right)\cdot\left(-10^2\right)+\left(-5\right)^2\\ =6\cdot\left(-16\right)\cdot\left(-100\right)+25\\ =9600+25\\ =9625\)
\(6.\left(-4\right)^2.\left(-10\right)^2+\left(-5\right)^2=6.16.100+25=9600+25\\ =9625\)
