Answer 1

C) 3×{11+2×[270-2×(1275-38×30)]}+145-5³

=3×{11+2×[270-2×(1275-1140)]}+145-125

=3×[11+2×(270-2×135]) +20

=3×[11+2×(270-270]) +20

=3×(11+2×0) +20

=3×(11+0) +20

=3×11+20

=33+20=53

D) 8×{14+3×[28+6×(1432-42×33)]}+11²-5 la 10

=8×{14+3×[28+6×(1432-1386)]}+121-3125

=8×[14+3×(28+6×46)]+121-3125

=8×[14+3×(28+276)]+121-3125

=8×(14+3×304)+121-3125

=8×(14+912)+121-3125

=8×926+121-3125

=7408+121-3125

=7529-3125=4404

E) {253+15×[21×(282÷47+1215÷27) ÷18÷15²]×10}+14la a doua

={253+15×[21×(6+45) ÷18÷225]×10}+196

=[253+15×(21×51÷18÷225) ×10]+196

=[253+15×(1071÷18÷225) ×10]+196

=[253+15×(595÷225) ×10]+196

=(253+15×2,975×10) +196

=(253+44,625×10) +196

=(253+446,25)+196

=699+196=895

și pe ultima nu o stiu scuze sper ca team ajutat
