Explicație pas cu pas:

b)

$[(17^2 - 11*3):8^2+3*16]:13 = [(289 - 33):64+48]:13 = (256:64+48):13 = (4+48):13 = 52:13=4$

c)

$[12*15-(2^4*5^4-98^2):2^2:3^2]:13=[180-(2^{2{^2}}*5^{2{^2}}-98^2):4:9]:13=[180-(4^2*25^2-98^2):4:9]:13=[180-(100^2-98^2):4:9]:13=[180-(100-98)(100+98):4:9]:13=(180-2*198:4:9):13=(180-396:4:9):13=(180-99:9):13=(180-11):13=169:13=13$
