\(32^9:64=\left(2^5\right)^9:2^6=2^{45}:2^6=2^{45-6}=2^{39}\)

32⁹:64

= (2⁵)⁹:2⁶

= 2⁴⁵:2⁶

= 2^45-6

= 2³⁹

= a*3 đó bạn

a^3

mk cũng ko biết có đúng ko

a^4:a=a^3 k mình

​

a) 11^5

b) 17^2 

c) 4^2 

d) a^4 

\(9^5:3^7=\left(3^2\right)^5:3^7=3^{10}:3^7=3^3\)

\(8^6:4^8=\left(2^3\right)^6:\left(2^2\right)^8=2^{18}:2^{16}=2^2\)

\(25^7:125^3=\left(5^2\right)^7:\left(5^3\right)^3=5^{14}:5^9=5^5\)

Chúc bạn học tốt !

(ab) x (ab)²

= (ab)¹ x (ab)²

= (ab)¹⁺²

=(ab)³

hok tốt..........

ab . (ab)² = (ab)²⁺¹ = (ab)³

(ab)³

5^13: 5⁷ = 5 ^13-7=5^6=15625

a⁹.a.a⁵=a⁹⁺¹⁺⁵=a¹⁵

Trả lời :

5¹³ : 5⁷ = 5^13-7 = 5⁶

a⁹ . a . a⁵ = a⁹⁺¹⁺⁵ = a¹⁵

~~Học tốt~~

\(5^{13}:5^7=5^{13-7}=5^6\)
