\(\left(3x+1\right)^5=\left(\frac{1}{2}\right)^5\)
\(\Rightarrow3x+1=\frac{1}{2}\)
\(\Rightarrow3x=\frac{1}{2}-1=\frac{-1}{2}\)
\(\Rightarrow x=\frac{-1}{2}:2=\frac{-1}{6}\)

Có nghĩa , nhưng về mặt lý thuyết thì sai rồi 

gọi số cần tìm là a, ta có

a :29 dư 5; a :31 dư 28

a=29p+5; a=31q+28

khi do ta co: 29p+5 = 31q+28 (*)

=> 29(p-q) = 2q+23

=> 28(p-q) + (p-q) - 1 = 2q +22

ve phai chia het cho 2 nen [(p-q)-1] cung chi het cho 2

ma do a la so tu nhien nho nhat nen [(p-q)-1] = 0 => p = q+1 thay vao (*)

ta duoc q = 3 => p = 4. Vay so a = 31*3+28 = 121 hay a = 4*29 + 5 = 121

\(a>x^2=16\)
\(x^2=4^2=\left(-4\right)^2\)
\(\Rightarrow x=\pm4\)
\(b>x^3=-8\)
\(x^3=\left(-2\right)^3\)
\(\Rightarrow x=-2\)

Ta có góc A và B phụ nhau 
=> Góc A + góc B = 180 độ 
Áp dụng tính chất của dãy tỉ số bằng nhau , ta có : 
\(\frac{A}{5}=\frac{B}{4}=\frac{180}{9}=20\)
=> Góc A = 20 . 5 = 100 
Góc B = 20 . 4 = 80
