Toán Lớp 6: 72 + [ 62 – ( 102 – 4 . 16 )] x + 8 = 10
Comments ( 2 )
$72+\left[62-\left(102-4\cdot \:16\right)\right]$
$=72+24$
$=96$
$————–$
$x+8=10$
$⇒x+8-8=10-8$
$⇒x=2$
Vậy $x=2$
Answer
72 + [62 – (102 – 4 . 16)]
= 72 + [62 – (102 – 64)]
= 72 + [62 – 38]
= 72 + 24
= 96
_____________________
x + 8 = 10
=> x = 10 – 8
=> x = 2
Vậy x = 2
