Question

resolva essas expressões númericas,como fazer:
5*[16-(2+3*4)+8]
54 dividido {9+[15/5+(23+14)]-15}

Answer 1

$a) \\ 5.[16-(2+3.4)+8]=5.[16-(2+12)+8]=5.[16-14+8]= \\ \\ =5.[16-22]=5.(-6)=-30 \\ \\ \\ b) \\ \frac{54}{9+[ \frac{15}{5}+(23+14)]-15 } = \frac{54}{9+[3+37]-15} = \\ \\ = \frac{54}{9+40-15} = \frac{54}{9+40-15} = \frac{54}{49-15} = \frac{54}{34} = \frac{27}{17}$
