Exercise 11 (B) | Q 6.4

Write the degree of the following polynomial: 2y²z + 9yz³

Write numerical co-efficient of the following: - y

In -5x³y²z⁴ ; write the coefficient of: z² Also, write the degree of the given algebraic expression.

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

Simplify: `"b"("2b" - 1/"b") - "2b"("b" - 1/"b")`

Simplify: 5a – [6a – {9a – (10a – `bar("4a" - "3a"))}]`

Simplify: `"p"^2 - ["x"^2 - {"x"^2 - ("q"^2 - bar("x"^2 - "q"^2)) - "2y"^2}]`

Simplify: `8"x" - ["4y" - {"4x" + ("2x" - bar"2y - 2x")}]`

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

0.1 y + 0.01 y²

Write the coefficient of x² in the following:

1 + 2x + 3x² + 4x³
