3^2=3x3=9

Đáp số 9

Tk mk nha mk tk lại

dap an bang 9

9 nha các bạn nhớ k cho mình nhé ai , mình sẽ tích lại

1+1=2

tk cho mk nha!

trả lời

1+1=2

chị e 3 đúng r nha chị vs

tk ho mik di cac bn

k dau=6 tk

tk 2=5 tk

tk 3=4 tk

nhanh nha cac bn

1+1=2

nhanh nao cac bn

luongkun!

2

học tốt

=2 nha bạn

tk cho mình r mk lại cho

đổi càng nhiều càng tốt

2³ + 3²

= 2 x 2 x 2 + 3 x 3

= 8 + 9

= 17

k cho tớ nha bn

2^3+3^2

=8+9

=17

k mk nhe

rui mk k lai chp

2³+3²

=8+9

=17

x + 80 = 90 - 10

x + 80 = 80

x = 80 - 80 

x = 0

x = 0

kick nha

mik trc nha

bằng 29nha bn mik k bn bn k lại mik nha giữ lời hứa đó

20+09=29

20+09=29

58 x 46 = 2668 ~nhe

58*46=2668

 58 x 46 = 2668 nhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

nha bạn đúng thì k

minh k ban ban k lai minh nha

roi do

Tính A với:A=1+2+2²+2³+...+2⁹⁹+2¹⁰⁰

=>2A=2+2²+2³+2⁴+...+2¹⁰⁰+2¹⁰¹

=>2A-A=(2+2²+2³+2⁴+...+2¹⁰⁰+2¹⁰¹) - (1+2+2²+2³+...+2⁹⁹+2¹⁰⁰)

A=2¹⁰¹-1

Vậy A=2¹⁰¹-1

2A=2^2+2^3+2^4+.............+2^102

=> 2A-A=2^102-1

=> A=2^102-1

Ai tk mik, mik tk lai nha
