bạn làm như bạn gia hân là đúng nhé

giải giúp mình bài 2 trên với ạ

2 mũ 4 - 4 mũ 2=16-16=0

( 2 mũ 17 + 17 mũ 2 ) . ( 9 mũ 15 - 3 mũ 15 ).0=0

đ/s: 0

(2¹⁷+17²).(9¹⁵-3¹⁵).(2⁴-4²⁰)

b1:4^10.8^15 = (2^2)^10.(2^3)^15 = 2^20.2^45 = 2^65

(2¹⁷ + 15³).(3⁴⁵ - 6⁵).(2⁴ - 4²)

= (2¹⁷ + 15³).(3⁴⁵ - 6⁵).(16 - 16)

= (2¹⁷ + 15³).(3⁴⁵ - 6⁵).0

= 0

\(4^2\cdot120-4^3\cdot17+4^2\cdot34\)

\(=4^2\left(120-4\cdot17+34\right)\)

\(=16\left(120-68+34\right)\)

\(=16\cdot86=1088\)

\(7^3\cdot9+3^2\cdot7^4-45\cdot539\)

\(=7^3\cdot9+9\cdot7^4-45\cdot7^2\cdot11\)

\(=7^2\left(7\cdot9+9\cdot7^2-45\cdot11\right)\)

\(=49\left(63+9\cdot49-495\right)\)

\(=49\left(63+441-495\right)\)

\(=49\cdot9=441\)

\(5\cdot10^4+4\cdot10^3+6\cdot10^2+5\cdot10+9\)

\(=10\left(5\cdot10^3+4\cdot10^2+10\cdot6\right)+9\)

\(=10\left(5\cdot1000+4\cdot100+60\right)+9\)

\(=10\left(5000+400+60\right)+9\)

\(=10\cdot5460+9=54600+9=54609\)

a) 3 . 5² + 15 . 2² - 26 : 2

= 3 . 25 + 15 . 4 - 26 : 2

= 75 + 60 - 13

= 135 - 13

= 122

b) 5³ . 2 - 100 : 4 + 2³ . 5

= 125 . 2 - 100 : 4 + 8 . 5

= 250 - 25 + 40

= 225 + 40

= 265

c) (5¹⁹ : 5¹⁷ + 3 ) : 7

= (5² + 3) : 7

= (25 + 3) : 7

= 28 : 7

= 4

d) 7⁹: 7⁷ - 3² + 2³ . 5²

= 7² - 3² + 2³ . 5²

= 49 - 9 + 8 . 25

= 40 + 200

= 240

e) 7⁹¹ : 7⁸⁹ + 5 . 5² - 124

= 7² + 5 . 25 - 124

= 49 + 125 - 124

= 174 - 124

= 50
