a.123-5.(x+4)=38
b.(3.x-24).73=2.74
a,123-5(x+4)=38
b,(3.x-2^4).7^3=2.7^4
tìm x
123 - 5. ( x+4 ) = 38
( 3x - 2^4 ) . 7^3 = 2 . 7^4
Tìm x
a, 123 - 5 . ( x + 4 ) = 38
b, ( 3x - 24 ) . 73 = 2 . 74
c, ( x : 3 - 4 ) . 5 = 15
a, 123 - 5 . ( x + 4 ) = 38
b, ( 3x - 24 ) . 73 = 2 . 74
c, ( x : 3 - 4 ) . 5 = 15
[ 8 x - 120 ÷ 4 ] ×3^3=3^6
123-5 (x+4)=38
(3x- 2^4)×7^3=2×7^4
Bài 2. Tìm x biết:
a, 128 - 3(x + 4) = 23 d, 720 : [41 - (2x - 5)] = 2 3 .5
b, [(4x + 28).3 + 55] : 5 = 35 e, 123 – 5.( x + 4 ) = 38
c, (12x - 4 3 ).8 3 = 4.8 4 g, ( 3x – 2 4 ) .7 3 = 2.7 4
123 - 5 . [ x + 4 ] = 38
[ 3x - 2 mũ 4 ] . 7 mũ 3 = 2. 7 mũ 4
5.2 mũ x + 1 = 80
2 mũ x + 2 mũ x + 3 = 576
5 mũ 2x - 3 - 2.5 mũ 2 = 5 mũ 2 .3
