k nhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

1 x 1 = 1² = 1

13 x 13 = 13² 

3 x 3 x 3 = 3³ = 27 

k mik nha

ko biết viết sao bài đó dễ mà

1x1=1

13x13=169

3x3x3=27

a) ( 3 x 3 x 3 x 3 x 3 ) x ( 4 x 4 x 4 x 4 x4 ) = 243 x 1024 = 248832 vi 3^5 = 5 con 3 x nhau = 243, 4^5 = 5 con 4 x nhau = 1024

             3^5                            4^5

b) ( 8 x 8 x 8 x 8 x 8 ) x ( 2 x 2 x 2 ) = 32768 x 8 = 262144 vi 8^5 =5 con 8 x nhau = 32768, 2^3 = 3 con 2 nhan nhau = 8 

              8^5                        2^3

k cho tk nha

a﴿ ﴾ 3 x 3 x 3 x 3 x 3 ﴿ x ﴾ 4 x 4 x 4 x 4 x4 ﴿

cho tk nha

\(2^4.2^9=2^{4+9}=2^{13}\)

2⁴.2⁹=2⁴⁺⁹=2¹³

bằng 2 mũ 13 

\(0,25.2^8\)

\(=\frac{1}{4}.2^8\)

\(=\frac{2^8}{2^2}\)

\(=2^{8-2}\)

\(=2^6\)

=2⁶ hihi

0,25*2^8

=2^(-2)*2^8

=2^6

9⁸ : 3² = 9⁸ : 9 = 9^8-1 = 9⁷

\(9^8=\left(3^3\right)^8=3^{11}\)

\(\Rightarrow9^8:3^2=3^{11}:3^2=3^9\)

tíc mình 

nha

9⁸ :3² = 9⁸ : 9

         = 9^8-1

           =9⁷
Đúng không hả

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