Question

$\sqrt{25} + 81 \div 3$

$13 + 63 \div 7 + 2 \times 5$

$(12 \times 5) -( 8 {}^{2} \div 16)$

$5 {}^{4} + ( \sqrt{100} \times (32 - 17))$

Answer 1

Resposta:

a) √25+81/3 =5+27 =32

b)13+63/7+2*5  =13+ 9+10 =32

c) (12*5)-(8²/16) = 60-64/16 =60  =60-4 =56

d) 5^4 +(√100 * (32-17)) = 625+(10* 15)

=625+150  = 775
