\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
Bài làm
A = 3¹° . 11 + 3¹° . 5 / 39 . 2⁴
A = 3¹° . ( 11 + 5 ) / 39 . 16
A = 3¹° . 16 / 39 . 16
A = 3¹° / 39
A = 3
Vậy A = 3
Mk lm bằng đt nên k vt đc phân số nha.
A=3^10.11+3^10.5/3^9.2^4
A=3^10.(11+5)/3^9.2^4
A=3^10.16/3^9.16
A=3^10/3^9
A=3
A=\(\frac{3^{10}\cdot11+3^{10}\cdot5}{3^9\cdot2^4}\)
A=\(\frac{3^{10}\cdot\left(11+5\right)}{3^9\cdot2^4}\)
A=\(\frac{3^{10}\cdot16}{3^9\cdot2^4}\)
A=\(\frac{3^{10}\cdot2^4}{3^9\cdot2^4}\)
A=\(\frac{3^{10}}{3^9}\)
A=3
Tính : A= \(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=?\)
\(=\frac{3^{10}\left(11+5\right)}{3^9.16}=\frac{3^{10}.16}{3^9.16}=3\)
\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.16}{3^9.2^4}=\frac{3^9.2^4.3}{3^9.2^4}=3\)
Tính tổng M = \(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(A=\frac{3^{10}\left(11+5\right)}{3^9.2^4}=\frac{3^{10}.2^4}{3^9.2^4}=3\)
3 bạn ạ
Tk cho mk nhé !!!!!! Chúc bạn năm mới vui vẻ
Thank you very much
\(M=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
M=3^10.11+3^10.5 / 3^9.2^4
=3^10(11+5) / 3^9.2^4
=3^10.2^4 /3^9.2^4
=3^10/3^9
=3
A=\(\dfrac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(A=\dfrac{3^{10}.11+3^{10}+5}{3^9.2^4}\\ A=\dfrac{3^{10}.\left(11+5\right)}{3^9.16}\\ A=\dfrac{3^{10}.16}{3^9.16}\\ A=3\)
A = \(\dfrac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(A=\dfrac{3^{10}.\left(11+5\right)}{3^9.16}\)
\(A=\dfrac{3^{10}.16}{3^9.16}\)
\(A=\dfrac{3^{10}}{3^9}=3\)
Tính giá trị biểu thức:
\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(=\frac{3^{10}.\left(11+5\right)}{3^9.2^4}\)
\(=\frac{3^{10}.16}{3^9.2^4}\)
\(=\frac{3^{10}.2^4}{3^9.2^4}=3\)
3^10.(11+5) =3.16
3^9 . 2^4 1.16 bỏ số 16 thì được kết quả bằng 3
Tính giá trị các biểu thức sau
\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
Ta có : \(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.\left(11+5\right)}{3^9.16}=\frac{3^{10}.16}{3^9.16}=3\)3
\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.\left(11+5\right)}{3^9.2^4}\) \(=\frac{3^{10}.16}{3^9.2^4}=\frac{3^{10}.2^4}{3^9.2^4}=3\)
Tớ đánh sai nha, đáp án là 3.

a)\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
b)100+98+96+.......+2-97-95-.....-1
a) \(\frac{3^{10}.\left(11+5\right)}{3^9.16}\)=\(\frac{3^{10}.16}{3^{10}.16}\)=1
a) \(\frac{3^{10}.\left(11+5\right)}{3^9.16}=\frac{3^{10}.16}{3^9.16}=\frac{3^{10}}{3^9}=3\)
\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)
\(=\frac{3^{10}.\left(11+5\right)}{3^9.16}\)
\(=\frac{3^{10}.16}{3^9.16}\)
\(=\frac{3^{10}}{3^9}\)
\(=3\)
