Start inside the deepest parentheses:
-1[-2(-3)^3]^2 = -1[-2(-27)]^2 = -1[54]^2 = -2916
-3{3-2{10-3(-2)^2}^2]^2
= -3{3-2{10-3*4}^2]^2
= -3{3-2{10-12}^2]^2
= -3{3-2{-2}^2]^2
= -3{3-2*4]^2
= -3{3-8]^2
= -3(-5)^2
= -3*25
= -75
-3[4-7(-3-5)]-(-5)^2
= -3[4-7(-8)]-25
= -3[4+56] - 25
= -3*60 - 25
= -180 - 25
= -205
simplify the following problems. show all work
1) -1[-2(-3)^3]^2
2) -3{3-2{10-3(-2)^2}^2]^2
3) -3[4-7(-3-5)]-(-5)^2
