1) (-3)^(-2) + 0.3^(-1) - (√5)^0= (-1/9) + 10/3 - 1= -1/9 + 10/3 - 1= -1/9 + 30/9 - 9/9= (30 - 10 - 9)/9= 11/9
2) 4(-3) - 5(-3)^2= -12 - 5(9)= -12 - 45= -57
2(-3) - 3= -6 - 3= -9
Therefore, the final result is -57/-9 = 6.33.
1) (-3)^(-2) + 0.3^(-1) - (√5)^0
= (-1/9) + 10/3 - 1
= -1/9 + 10/3 - 1
= -1/9 + 30/9 - 9/9
= (30 - 10 - 9)/9
= 11/9
2) 4(-3) - 5(-3)^2
= -12 - 5(9)
= -12 - 45
= -57
2(-3) - 3
= -6 - 3
= -9
Therefore, the final result is -57/-9 = 6.33.
