Question

4-Determine os valores exatos das sentenças a)2³+5 B)6:(5⁰+1)+(3¹+2²) C)10:(5⁰+1)+3³ D)2+[10²+5+(5⁰+1⁰+4⁰)+6] e)15+[2⁰+[6⁰+2¹+2²]+4² F)25+[6²÷0]-3​

Answer 1

$a)2^3+5$

$8+5=13$

$b)6:(5^0+1)+(3^1+2^2)$

$6:(1+1)+(3+4)$

$6:2+7$

$3+7=10$

$c)10:(5^0+1)+3^3$

$10:(1+1)+27$

$10:2+27$

$5+27=32$

$d)2+[10^2+5+(5^0+1^0+4^0)+6]$

$2+[100+5+(1+1+1)+6]$

$2+[100+5+3+6]$

$2+[105+9]$

$2+114=116$

$e)15+[2^0+[6^0+2^1+2^2]+4^2$

$15+[1+[1+2+4]+16]$

$15+[1+7+16]$

$15+[8+16]$

$15+24=39$

$f)25+[6^2:0]-3$

$25+[36:0]-3$

$25+0-3$

$25-3=22$
