Exercise 11 (F) | Q 11

Identify term which contain y² and give the coefficient of y².

8 - xy²

Constant is only 8 other is variable 3x² × 5x

For the following monomials, write its degree: 3m³n⁴

In -5x³y²z⁴ ; write the coefficient of -5xy²z. Also, write the degree of the given algebraic expression.

Add : - 9x, 3x and 4x

Subtract the second expression from the first:

a³ - 1 + a, 3a - 2a²

Simplify: `10 – {4"a" – (7 – bar ("a" - 5) - (5"a" - bar(1 + "a")))`

Find the missing term

_________ × (−15m²n³p) = 45m³n³p²

Identify the numerical coefficient of term (other than constant) in the following expression:

2(l + b)

Write the coefficient of x² in the following:

1 + 2x + 3x² + 4x³
