Tìm x :
8 x 6 + 288 : ( x - 3 ) mũ 2 = 50
8×6+288:(x-3)²=50
8×6+288:(x—3)^2=50
Tìm x
tìm số tự nhiên x, biết: 8 x 6 + 288 : ( x - 3 )2 = 50
tính
a,8.6+288:(x-)^2=50
b,{x^2-[6^2-(8^2-9.7)^3-7.5]^3-5.3)^3=1^3
8 . 6 + 288 : ( x - 3 )2 = 50
Giúp mk vs! Cám ơn trc
bài 2 tim x , biết :
a ) 8 . 6 + 288 : ( x - 3 ) 2 = 50
8 . 6 + 288 : ( x - 3 )2 = 50
{ x2 - [ 62 - ( 83 - 97)3 - 7 . 5 ]3 = 1
GIÚP MÌNH NHA CÁC BẠN
a,23.6+288:(x-3)2=50
b, {x2-[62-(82-32.7)3-7.5]3-5.3}3=1
c,32.5:x=(22.15-32.5):3
