Question

CALCULE AS EXPRESSOES;A) (5+1 )² -5.6 B) 17-(2.2)²+ (4-1)³ C) (8:2)³ +(8-2)²

Answer 1

Resposta:

$A)\\ \\(5+1)^{2}-5.6=5^{2}+2.5.1+1^{2}-5.6=25+10+1-30=6\\ \\B)\\ \\17-(2.2)^{2}+(4-1)^{3}=17-4^{2}+4^{3}-3.4^{2}.1+3.4.1^{2}-1^{3}=\\ \\17-16+64-48-1=16\\ \\C)\\ \\(\frac{8}{2})^{3}+(8-2)^{2}=\frac{512}{8}+8^{2}-2.8.2+2^{2}=64+64-32+4=100$
