Exercise 11 (B) | Q 4.1

Write numerical co-efficient of the following: – 9a²b³

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

Simplify : 3m + 12m – 5m

Find the sum of: 4x²+ 8xy – 2y² and 8xy – 5y² + x²

Subtract the second expression from the first:

5a + b, - 6b + 2a

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

The numerical co-efficient of the term −xy is __________

To add two like terms, its coefficients can be added

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

5y² + 7x

Identify term and factor in the expression given below:

`3/4 x + 1/4`
