Answer 1

a) 3. 5 ^ 2 + 15. 2 ^2 - 26 : 2

= 15 ^ 2 + 15. 4 - 13

= 225 + 60 - 13

= 272

b) 5 ^ 3. 2 - 100 : 4 + 2 ^ 3. 5

= 125. 2 - 25 + 40

= 250 - 25 + 40

= 265

c) 6 ^ 2 : 9 + 50. 2 - 3 ^ 3. 3

= 36 : 9 + 100 - 81

= 4 + 100 - 81

= 23

d) 3 ^ 2. 5 + 2 ^ 3 . 10 - 81 : 3

= 45 + 8 . 10 - 27

= 53 + 80 - 27

= 160

e) 5 ^ 13 : 5 ^ 10 - 25. 2 ^ 2

= 1220703125 : 9765625 - 25. 4

= 125 - 100

= 25

f) 20 : 2 ^ 2 + 5 ^ 9 : 5 ^ 8

= 20 : 4 + 1953125 : 390625

= 5 + 5

= 10

g) 100 : 5 ^ 2 + 7. 3 ^ 2

= 100 : 25 + 7 . 9

= 4 + 63

= 67

h) 84 :4 + 3 ^ 9 : 3 ^ 7 + 5 ^ 0

= 21 + 19683 : 2187 + 1

= 21 + 9 + 1

= 31

i) 29 - [ 16 + 3. ( 51 - 49) ]

= 29 - [ 16 + 3. 2 ]

= 29 - 22

= 7

Mình làm xong rồi nhé!

Answer 2

29*(-49)+(-29)*51
