Trả lời :
a) 43 . 101 - 64
= 64 . 101 - 64
= 64 . ( 101 - 1 )
= 64 . 100 = 6400
b) \(\frac{5^8}{5^5}+3^2.3^3-\left(30-19\right)^2\)
= 53 + 35 - 112
= 125 + 243 - 121
= 247
a) 43 .101 - 64 =
= 43 . 101 - 43
= 43 .( 101 - 1 )
= 43 .100
= 6400
c) 100 - [( 64 - 48 ) . 5 + 88 ] : 28
= 100 - ( 16 . 5 + 88 ) : 28
= 100 - ( 80 + 88 ) : 28
= 100 - 168 : 28
= 100 - 6
= 94
b) 58 : 55 + 32 x 33 - ( 30 - 19 )2
= 53 + 35 - 112
= 125 + 243 - 121
= 247
a)43.101 - 64
= 64 . 101 - 64
= 64 . 100
= 6400
b) 58 / 55 +32 ×33-(30 - 19)2
= 55.53 / 55 + 35 - 12
= 53 + 35 - 12
= 125 + 243 - 1
= 368 - 1
= 367
c) 100 - [ ( 64 - 48 ) x 5 + 88 ] : 28
= 100 - ( 16 x 5 + 88 ) : 28
= 100 - ( 80 + 88 ) : 28
= 100 - 168 : 28
= 100 - 6
= 94
HOk tốt!!!!!!!!!!
c)100 - [ (64 - 48 ) x 5 +88 ] : 28
= 100 - [ 16 x 5 + 88 ] : 28
= 100 - [ 80 + 88 ] : 28
= 100 - 168 : 28
= 100 - 6
= 94
nha bạn chúc bạn học tốt ạ
