các câu sau tương tư nha bạn

a)

d) =

e) =

25⁴ . 2⁸ = (5²)⁴ . 2⁸ = 5^2.4 . 2⁸ = 5⁸ . 2⁸ = (5 . 2)⁸ = 10⁸

25⁴.2⁸=(5²)⁴.2⁸=5⁸.2⁸=(5.2)⁸=10⁸=100000000

=10.2>8=20>8

Trả lời:

a, \(15^8.9^4\)

\(=15^8.\left(3^2\right)^4\)

\(=15^8.3^8\)

\(=45^8\)

b, \(27^2:25^3\)

\(=\left(3^3\right)^2:\left(5^2\right)^3\)

\(=3^6:5^6\)

\(=\left(\frac{3}{5}\right)^6\)

Hok Tốt!!!!

a. 15⁸ . 9⁴

= 15⁸ . (3²)⁴

= 15⁸.3⁸

= (15.3)⁸

= 45⁸

b. 27² : 25³

= (3³)² : (5²)³

= 3⁶ : 5⁶

= \(\left(\frac{3}{5}\right)^6\)

12⁸.9¹²

= (12²)⁴.(9³)⁴

= 144⁴.729⁴

= (144.729)⁴

= 104976⁴
