Question

[Raiz quadrada 100-(2 elevado a quarta potência -8).2-(19-7):6}2+12=

Answer 1

[√100 - (2⁴ - 8 ) • 2 - ( 19 - 7) : 6] 2 + 12 =
= [ 10 - (16 - 8) • 2 - 12 : 6 ] 14
= [ 10 - 8 • 2 - 2 ] 14
= [10 - 16 - 2 ] 14
= [ - 6 - 2 ] 14
= - 8 + 14
= 6

Answer 2

[√100 - (2⁴ - 8 ) • 2 - ( 19 - 7) : 6] 2 + 12 =

= [ 10 - (16 - 8) • 2 - 12 : 6 ] 14

= [ 10 - 8 • 2 - 2 ] 14

= [10 - 16 - 2 ] 14

= [ - 6 - 2 ] 14

= - 8 + 14

= 6
