Find the coefficient in the given terms.(i) x in 4x(ii) y2, x2 in 9x2y2(iii) x3, y3 and x3y3 in \(\frac{-8}{5}\)x3y3(iv) a2 and b2 in \(\frac{9a^2b^2}{13}\)

Answer»

(i) Coefficient of x in 4x is 4.

(ii) Coefficient of y² in 9x²y² is 9x²

Coefficient of x² in 9x²y² is 9y²

(iii) Coefficient of x³ in \(\frac{-8}{5}\)y³y³ is \(\frac{-8}{5}\)x³

Coefficient of x³y³ in \(\frac{-8}{5}\)x³y³ in \(\frac{-8}{5}\)y³

(iv) Coefficient of a²in \(\frac{9a^2b^2}{13}\) is \(\frac{9}{13}\)b²

Coefficient of b² in \(\frac{9a^2b^2}{13}\) is \(\frac{9}{13}\)a²
