Question

10+[20+(6)²-15]=
21+[54+(12÷2)¹-50=
+20+[+50+(8)²-25=
+25+{+10+[-12+(-5)²-20)]}=​

Answer 1

Explicação passo-a-passo:

10 + [ 20 + 36 - 15]=

10 + [ 56 -15]=

10 + 41=

51

21 + [ 54 + (6)¹ -50]=

21 + [ 53 +6 - 50]=

21 + [ 59 - 50]=

21 + 9=

30

20 + [ 50 + 64 -25]=

20 + [ 114 -25]=

20 + 89=

105

25 + { 10 + [ -12 + 25 - 20]}=

25 + { 10 + [ -32 +25]}=

25 + { 10 + [ -7]}=

25 + { 10 - 7}=

25 + 3=
