2^0 x 2^9 : 8 

= 1 x 512 : 8 

= 64

nha bạn 

Bằng 64

\(35=\left(\sqrt{35}\right)^2\)

\(184=\left(2\sqrt{46}\right)^2\)

\(372=\left(2\sqrt{93}\right)^2\)

\(88=\left(4\sqrt{11}\right)^2\)

\(832=\left(8\sqrt{13}\right)^2\)

\(35=5\cdot7\)

\(184=2^3\cdot23\)

\(372=2^2\cdot3\cdot31\)

\(88=2^3\cdot11\)

\(832=2^6\cdot13\)

\(A=1+3+3^2+...+3^{2002}\)

\(3A=3+3^2+3^3+...+3^{2003}\)

\(2A=3A-A=3^{2003}-1\Rightarrow A=\dfrac{3^{2003}-1}{2}\)

A = \(\dfrac{3^{2003}-1}{2}\)

mình đang rất cần

trước khi giảm giá giá của nó là

161000x8=1288000(đồng)

đáp số 1288000 đồng

\(\left(\dfrac{1}{4}\right)^{2n}=\left(\dfrac{1}{8}\right)^2\)

\(\Rightarrow\left(\dfrac{1}{2}\right)^{2.2n}=\left(\dfrac{1}{2}\right)^{3.2}\)

\(\Rightarrow\left(\dfrac{1}{2}\right)^{4n}=\left(\dfrac{1}{2}\right)^6\)

\(\Rightarrow4n=6\)

\(\Rightarrow n=\dfrac{6}{4}=\dfrac{3}{2}\)

n = 3/2

2⁶:4²=4. Tk mik nha!!

2⁶ : 4²

= 2⁶ : ( 2² )²

= 2 ⁶ : 2⁴

= 2²

2^6:4^2=2^6:(2^2)^2=2^6:2^4=2^2
