c) 12: (2+1)x4 + 3 =

d) 24 x 56=

e) 2x3x 52=

f) V25+42x 3 : 23-149=

g) 22x 32.545​

Answer 1

Resposta:

a)

$52 - \sqrt{8 } + 56 \div 2 \\ 52 - 2 \sqrt{2} + 28 \\ 80 - 2 \sqrt{2}$

b)

$(23 - 32).4 \\ - 9.4 \\ - 36$

c)

$12 \div (2 + 1).4 + 3 \\ 12 \div 3.4 + 3 \\ 16 + 3 \\ 19$

d)

$24.56 \\ 1344$

e)

$2.3.52 \\ 6.52 \\ 312$

f)

$\sqrt{25} + 42 \times 3 \div 23 - 149 \\ 5 + \frac{42.3}{23} - 149 \\ 5 + \frac{126}{23} - 149 \\ - 149 + \frac{126}{23} \\ - \frac{3186}{23}$

g)

$22.32.545 \\ 11990.32 \\ 383680$
