Question

A) 4 elevado a 2 -10+(2 elevado a 3 -5)
B)30+(6 elevado 2 ÷(5-3)+1)
C)20-(6-4×(10-3elevado a 2)+1)
D)50+(3elevado a 3 ÷(1+2)+4×3)
E)25+(3elevado a 3÷9+(3elevado a 2 ×5-3×(2elevado a 3 -5elevado a 1 )))

Answer 1

Olá, bom dia, boa tarde ou boa noite.

a) $4^{2}-10+(2^{3}-5)$
$16-10+(8-5)$
$6+3=9$

b) $30+(6^{2}:(5-3)+1)$
$30+(36:2+1)$
$30:(18+1)=30:19$

c) $20-(6-4.(10-3^{2})+1)$
$20-(6-4.(10-9)+1)$
$20-(6-4.1+1)$
$20-(6-4+1)$
$20-(2+1)$
$20-3=17$

d) $50+(3^{3}:(1+2)+4.3)$
$50+(27:3+12)$
$50+(9+12)$
$50+21=71$

e) $25+(3^{3}:9+(3^{2}.5-3.(2^{3}-5^{1})))$
$25+(27:9+(9.5-3.(8-5)))$
$25+(3+(45-3.3))$
$25+(3+(45-9))$
$25+(3+36)$
$25+39=64$
