Question

.1) Resolva as expressões numéricas.

a) [4+35:7+2x(15-9 x 1)]

b) {[20-(15-6+4)] x 12 - 10}

c) { 3x50 + [(16 + 64:16) x 3] x 2​

Answer 1

Resposta:A=21  B=74  C=270

Explicação passo a passo:

A = [4+35:7+2x(15-9x1)]

A= [4+35:7+2x6]

A= [4+5+12]

A= 21

B= {[20-(15-6+4)]x12-10}

B= {[20-13]x12-10}

B= {7x12-10}

B= 74

C= {3x50 + [(16+64:16)x3]x2}

C= {3x50 + [(20x3]x2}

C= {3x50 +60x2}

C= {150 +120}

C= 270
