3⁵ . 4⁵  = ( 3.4 )⁵ = 12⁵

8⁵ . 2³ = ( 2⁴ )⁵ . 2³ = 2²⁰ . 2³ = 2^{20 + 3} = 2²³

kb với mk nha các bạn

3⁵.4⁵.8⁵.2³= (3 . 4 . 8)³ . 8

\(16^3\cdot8^4=\left(2^4\right)^3\cdot\left(2^3\right)^4=2^{12}\cdot2^{12}=2^{24}\)

2⁵ . 4³ = 2⁵ . (2²)³ = 2⁵ . 2⁶ = 2^{5 + 6} = 2¹¹

\(2^{11}\)

\(16^2:4^2\)

\(=\left(4^2\right)^2:4^2\)

\(=4^4:4^2\)

\(=4^{4-2}\)

\(=4^2\)

==========

\(25^5:5^2\)

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

\(=5^{10}:5^2\)

\(=5^{10-2}\)

\(=5^8\)

============

\(9^8:3^2\)

\(=\left(3^2\right)^8:3^2\)

\(=3^{16}:3^2\)

\(=3^{16-2}\)

\(=3^{14}\)

\(a^6:a\)

\(=a^{6-1}\)

\(=a^5\)

giúp với alo mn ơi

a) 100 mũ 1

b) 5 mũ 2

c)100 mũ 1

Mình ko bk nên mk dùng là 100 mũ 1 nhé!

a, A = 3² . 4³ - 3² + 333

= 3² (4³ - 1) + 333

= 9 . 63 + 333

= 567 + 333

= 900 = 30²

b, B = 5 . 4³ + 2⁴ . 5 + 41

= 5 . 64 + 16 . 5 + 41

= 5 (64 + 16) + 41

= 400 + 41

= 441 = 21²

3⁶.9⁵=3⁶.(3²)⁵=3⁶.3¹⁰=3¹⁶

4⁸.2²=(2²)⁸.2²=2¹⁶.2²=2¹⁸

\(1)3^6.9^5\)

\(=3^6.\left(3^2\right)^5\)

\(=3^6.3^{10}\)

\(=3^{16}\)

\(2)4^8.2^2\)

\(=(2^2)^8.2^2\)

\(=2^{16}.2^2\)

\(=2^{18}\)

a) 27⁴.9² = 3¹².3⁴ = 3¹⁶

b) 4³.8⁴ = 2⁶.2¹² = 2¹⁸

c) 16⁵.64² = 2²⁰.2¹² = 2³²

9^8:3^2=9^8:9=9^7 

9^8=43046721

3^2=9

k mk nha!
