Ta có:

x5 . x4 = x(5+4) = x9

a4 . a = a(4+1) = a5

a) \({3.3^3} = 3.(3.3.3)= 3.3.3.3={3^4}\)

b) \({2^2}{.2^4}=(2.2).(2.2.2.2) =2.2.2.2.2.2= {2^6}\)

2.2.2.3.3.3.3 = 2³ . 3⁴

thì=2³.3⁴

dễ quá mà

2.2.2.3.3.3.3

= 2³ . 3⁴

~ ủng hộ nha~

− 8 . − 3 3 . + 125 = − 2 3 . − 3 3 .5 3 = − 2. − 3 .5 3 = 30 3

27. − 2 3 . − 7 . + 49 = 3 3 . − 2 3 − 7 − 7 2 = 3 3 . − 2 3 . − 7 3 = 3. − 2 . − 7 3 = 42 3 .

2^75 . 2^25

= 2^100

\(2^{75}.2^{25}=2^{75+25}=2^{100}\)

\(x^5.x^4=x^9\)

\(a^4.a=a^5\)

k nha năn nỉ

x⁴.x⁵=x⁹

a⁴.a=a⁵

x⁵.x⁴=x⁵⁺⁴=x⁹

a⁴.a=a⁴⁺¹=a⁵

Ai k mik đầu tiên thì mik sẽ k lại

x⁵ . x⁴ 

= x⁵⁺⁴ 

= x⁹ 

\(x^5.x^4=x^9\)
