Question

{[(45×5+175)×2-300]×15-75×75×4-6795​

Answer 1

$\left(\left(45\times \:5+175\right)\times \:2-300\right)\times \:15-75\times \:75\times \:4-6795$

$\left(\left(45\times \:5+175\right)\times \:2-300\right)\times \:15=$

$\left(45\times \:5+175\right)\times \:2 =$

$=2\left(225+175\right) =400\times \:2 =800$

$=15\left(800-300\right)$

$=500\times \:15 =7500$

$75\times \:75\times \:4=22500$

$=7500-22500-6795$

$=-21795$
