Explicație pas cu pas:
A) (2⁴X3⁸-3⁸):5-27³ = 3^8(2^4-1):5-27³=3^8·15:5-(3³)³=
=3^8·3-3^9=3^(8+1)-3^9=3^9-3^9=0
B) [(17²-11X3):8²+3:16]:13 =[(289-33):64+3:16]:13=(256:64+3:16):13=
=(4+3/16)·1/13=(64+3)/16·1/13=67/16·1/13=67/
C) [12X15-(2⁴X5⁴-98²):2²:3²]:13 =[180-(100²-98²):4:9]:13=
=[180-(100-98)(100+98)]:4:9:13=(180-396):4:9:13=-216:4:9:13=
=-54:9:13=-6/13
