(3x - 17 ) .16 = 4mũ3
( 3x - 17 ) . 16 = \(4^3\)<=> ( 3x - 17 ) . 16 = 64
<=> 3x - 17 = 64 : 16
<=> 3x = 4 + 17
<=> x = 21 : 3
<=> x = 7

4mũ3 - ( 5-2)mũ2 + 15mũ0
43 - ( 5 - 2 )2 + 150
= 64 - 32 + 1
= 64 - 9 + 1
= 55 + 1
= 56
k đúng cho mình nha !
-Học tốt-
43 - (5 - 2) 2 + 150
= 64 - 32 + 1
= 64 - 9 + 1
