Răspuns:

Explicație pas cu pas:

a) (-5)^3+(-2)^4=-125+16=-109

b) (-6)^3-5^2=-216-25=-241

c) -(-2)^5-2^4+(-2)^2=-(-32)-16+4=32-16+4=20

d) -3^2+(-4)^2-(-1)^99=-9+16-(-1)=7+1=8

e) (-8)^2-5^3-(-4^0)=64-125-(-1)=-61+1=-60

f) -(-2)^3·(-3)^2+20·(-1)^20=-(-8)·9+20·1=8·9+20=72+20=92

g) -2^6-(-8)^2:(-2^3)-(-6+5)^30=-64-64:(-8)-(-1)^30=-64+8-1=-57

h) -(-8+3)^2-0^13+(-1)^4^2-(-7^0)=-(-5)^2-0+1-(-1)=-25+2=-23

i) -(-3^4)+(-7-3)^3:(-8+18)^2=-81+(-10)^3:(10)^2=-81+(-10)=-81-10=-91

j) 2^5-(-8+5)^6:(-9)^3-(3-8+5)^17=32-(-3)^6:(-3)6-0^17=32-1=31
