AP State Syllabus 7th Class Maths Solutions 9th Lesson Algebraic Expressions Ex 9.2<\/h2>\n

Question 1.
\nState True or False and give reasons for your answer.
\n(i) 7x2<\/sup> and 2x are unlike terms.
\nAnswer:
\nTrue.
\n7x2<\/sup> and 2x have different algebraic factors and terms contain variables with different exponents.<\/p>\n

\"AP<\/p>\n

(ii) pq2<\/sup> arid – 4pq2<\/sup> are like terms.
\nAnswer:
\nTrue.
\npq2<\/sup> and – 4pq2<\/sup> are contain variables with same exponents. So, they are like terms.<\/p>\n

(iii) xy, – 12x2<\/sup>y and 5xy2<\/sup> are like terms.
\nAnswer:
\nFalse.
\nxy, – 12x2<\/sup>y and 5xy2<\/sup> are contain variables with different exponents. So, they are unlike terms.<\/p>\n

Question 2.
\nWrite like terms in the following :
\n(i) a2<\/sup>, b2<\/sup>, 2a2<\/sup>, c2<\/sup>
\nAnswer:
\nGiven a2<\/sup>, b2<\/sup>, 2a2<\/sup>, c2<\/sup>
\nLike terms: a2<\/sup>, 2 a2<\/sup>.<\/p>\n

(ii) 5x, yz, 3xy, \\(\\frac{1}{9}\\)yz
\nAnswer:
\nGiven 5x, yz, 3xy, \\(\\frac{1}{9}\\)yz
\nLike terms : yz, \\(\\frac{1}{9}\\)yz.<\/p>\n

(iii) 4m2<\/sup>n, n2<\/sup>p, – m2<\/sup>n, m2<\/sup>n2<\/sup>
\nAnswer:
\nGiven 4m2<\/sup>n, n2<\/sup>p, – m2<\/sup>n, m2<\/sup>n2<\/sup>
\nLike terms: 4m2<\/sup>n, – m2<\/sup>n.<\/p>\n

(iv) acb2<\/sup>, 2c2<\/sup>ab, 5b2<\/sup>ac, 3cab2<\/sup>
\nAnswer:
\nGiven acb2<\/sup>, 2c2<\/sup>ab, 5b2<\/sup>ac, 3cab2<\/sup>
\nLike terms: acb2<\/sup>, 5b2<\/sup>ac, 3cab2<\/sup>.<\/p>\n
