a) \(5^2.3^5.\left(\frac{3}{5}\right)^2\)
\(=25.243.\frac{9}{25}\)
\(=6075.\frac{9}{25}\)
\(=2187\)
b) \(4.32.2^3.\frac{1}{16}\)
\(=4.32.8.\frac{1}{16}\)
\(=128.8.\frac{1}{16}\)
\(=1024.\frac{1}{16}\)
\(=64\)
c) \(\left(-2\frac{1}{3}\right)^2.\left(-\frac{1}{4}\right)^2\)
\(=\frac{49}{9}.\frac{1}{16}\)
\(=\frac{49}{144}\)
d) \(\frac{9^5.5^7}{45^7}\)
\(=\frac{9^5}{9^7}\)
\(=\frac{1}{9^2}=\frac{1}{81}\)
e) 10³ + 5.10² + 5³
= 1000 + 5.100 + 125
= 1005 . 12500
= 13505
P/s: Mũ not ngũ ^^

X-31=5 NGŨ 2

ngũ hay mũ thế bn?

Trả lời

(2².2³/4².16)¹⁵:(2⁶/16²)¹⁰

=[2⁵/(2²)².2⁴ ]¹⁵:[2⁶/(2⁴)² ]¹⁰

=(2⁵/2⁸)¹⁵:(2⁶/2⁸)¹⁰

=1/8¹⁵:1/4¹⁰

=1/8¹⁵:1/8⁵

=1/8¹⁰

Ko chắc !

Mũ chứ k phải ngũ nhé !!!

\(\left(\frac{2^2.2^3}{4^2.16}\right)^{15}:\left(\frac{2^6}{16^2}\right)^{10}\)
\(=\left(\frac{2^5}{2^4.16}\right)^{15}:\left(\frac{2^6}{2^8}\right)^{10}\)
\(=\left(\frac{2}{16}\right)^{15}:\left(2^{-2}\right)^{10}\)
\(=\left(\frac{1}{8}\right)^{15}:2^{-20}\) -> đổi (1/8)¹⁵ = (1/2³)¹⁵ = 1/2⁴⁵ = 2^-45 
\(=2^{-45}:2^{-20}\)
\(=2^{-25}=\frac{1}{2^{25}}\)
Hơi tắt chút

\(24\cdot5^5+5^2\cdot5^3\)

\(=24\cdot5^5+5^{2+3}\)

\(=24\cdot5^5+5^5\)

\(=5^5\cdot\left(24+1\right)\)

\(=5^5\cdot25\)

\(=5^5\cdot5^2\)

\(=5^7\)

`@` `\text {Ans}`

`\downarrow`

`24 * 5^5 + 5^2 * 5^3`

`= 24*5^5 +`\(5^{2+3}\)

`= 24*5^5 + 5^5`

`= 5^5* (24+1)`

`= 5^5*25`

`= 5^5*5^2`

`= 5^7`

125 ngũ 4 chia 5 ngũ 8 bằng bao nhiêu

=81*(27+9^15):(3^5+3^32)

\(=\dfrac{3^4\cdot\left(3^3+3^{30}\right)}{3^5+3^{32}}=\dfrac{3^7\left(1+3^{27}\right)}{3^5\left(1+3^{27}\right)}=\dfrac{3^7}{3^5}=9\)

ngũ hay mũ vậy bạn

xin lỗi nhé mũ
