Question

Answer 1

\(a,=\left[\left(-4\right).\left(-250\right)\right].13\\ =1000.13=13000\\ b,=\left[\left(-8\right).\left(-125\right)\right].\left(-12\right)\\ =1000.\left(-12\right)=-12000\\ c,=37.\left(-84\right)+37.\left(-16\right)\\ =37.\left[\left(-84\right)+\left(-16\right)\right]\\ =37.\left(-100\right)=-3700\)
