Question

a (-113) + 55 + 113 - 155

b -25.17+17.(-75)

c 6⁸ : 6_⁶-3 [( -53) - ( -21 -53 )] + 2022⁰

Answer 1

\(a,\left(-113\right)+55+113-155=\left(-113+133\right)+\left(55-155\right)=0+\left(-100\right)=-100\\ b,-25.17+17.\left(-75\right)=17\left[\left(-25\right)+\left(-75\right)\right]=17.\left(-100\right)=-1700\)

\(c,6^8:6^6-3\left[\left(-53\right)-\left(-21-53\right)\right]+2022^0\\ =6^2-3\left(-53+21+53\right)+1\\ =36-3.21+1\\ =36-63+1\\ =-26\)

Answer 2

a(-113) + 55 + 113 - 155

=>(-113)+ 113+(55 - 155)

=>-100

b -25.17+17.(-75)

=>17(-25-75)

=>17. (-100)

=>-1700

c 6⁸ : 6_⁶-3 [( -53) - ( -21 -53 )] + 2022⁰

=>6²- 3[ -53 +21 +53 )]+1

=>36−3.21+1

=>36−63+1

=>−26
