Question

 

tìm x   80 - (4.5² - 3.2³)=2¹⁰-(x-4)

Answer 1

\(=2456\)

Answer 2

x = 2456 nha !

Answer 3

Theo đề ta có :  80 - (4.5² - 3.2³)=2¹⁰-(x-4)

\(\Rightarrow80-\left(4.25-3.8\right)=2^{10}-x+4\)

\(\Rightarrow80-4\left(25-6\right)=2^{10}-x+4\)

\(\Rightarrow80-76-4=2^{10}-x\)

\(\Rightarrow2^{10}-x=0\Rightarrow x=2^{10}=1024\)

Can you tk for me,Đức Đạt Đỗ (Đạt 301 Channel)!

Answer 4

80 - (4 . 5² - 3 . 2³) = 2¹⁰ - (x - 4)=

80 - (4 . 25 - 3 . 8) = 1024 - (x - 4)=

80 - (100 - 24) = 1024 - (x - 4)=

80 - 76 = 1024 - (x - 4)=

1024 - (x - 4) = 4

x - 4 = 1024 - 4

x - 4 = 1020

x = 1020 + 4

x = 1024
