(Khi đun nước đá ) là sao?????
 

Nước đá chuyển từ thể rắn sang thể lỏng rồi sang thể khí (hơi nước bay lên).

  15x5 x (x-25) = 225

x -25 = 225: 15:5

x - 25 = 3

x = 28

 15x5 x (x-25) = 225

x -25 = 225: 15:5

x - 25 = 3

x = 28

16¹⁰  > 3⁸                                                                                            5²⁴  > 11¹⁶

81⁴ > 243³                                                                                       7³⁰  > 4⁴⁵

825⁷  > 125⁴                                                                                   9¹⁴ < 4²¹

9²⁷ > 81¹⁵                                                                                        3¹⁸  < 2³⁰

2²⁷  < 3¹⁸                                                                                         5²⁷  > 49¹⁵

4³³  = 8²²

^{tích cho mình với nhé}

16¹⁰ = 2⁴⁰ = (2⁵)⁸ = 32⁸

81⁴ = 9⁸ = 3¹⁶ > 3¹⁵ = (3⁵)³ = 243³

vậy 81⁴ > 243³

825⁷ = 5² .33 < 5². 125 = 5².5³ = 5⁸ < 5¹² = (5³)⁴ = 125⁵

vậy 825⁷ < 125⁴

9²⁷ = 3⁵⁴ < 3⁶⁰ = (3⁴)¹⁵ = 81¹⁵

vậy 9^{27 <} 81¹⁵

388^oF = 197,(7)^oC

Chúc bạn học tốt.

😁😁😁

2^x + 2^x+3= 144

2^x + 2^x.2³ = 144

2^x + 2^x.8=144

2^x.(8+1)=144

2^x.9=144

2^x=144 : 9

2^x=16

2^x=2⁴

x=4

Ta có:

\(3^{x+2+4}.3^{x+1}=10.3^6\\ \Leftrightarrow3^{x+2+4+x+1}=10.3^6\\ \Leftrightarrow3^{2x+7}=10.3^6\\ \Leftrightarrow3^7.3^{2x}=10.3^6\\ \Leftrightarrow3.3^{2x}=10\\ \Rightarrow3^{2x}=\dfrac{10}{3}\\ \Rightarrow x=\dfrac{log_310-1}{2}\)

2x + 2x + 3 = 144

x(2+2) = 144 - 3

x(2+2) = 141

x4 = 141

x = 141 : 4

x = 35,25

Xin các bạn trả lời gấp.
