Mr. Sharma was assessing the students’ work on exponents. One of the response sheet was as follows : 2^{3}\times2^{8}=2^{8} 3^{2}\times4^{2}=(12)^{4} 3^{8} \div 3^{5}=3^{-2} 7^{20} \div 7^{14}=7^{6} 9^{3}\div18^{6}=( \frac{1}{2})^{3} On the basis of this response sheet Mr. Sharma can make the following observations :

Correct Answer is : Child has understood the law of exponents for the cases where the base is same and has missed the concept for the case where the base is different.

Child has understood the laws of exponents and can apply them well.

Child has understood the laws of exponents but has made clerical errors.

Child has understood the laws of exponents but has not practised the questions involving division of two numbers.

Child has understood the law of exponents for the cases where the base is same and has missed the concept for the case where the base is different.

Question : 48 of 120

Marks: +1, -0

Mr. Sharma was assessing the students’ work on exponents. One of the response sheet was as follows :

2^{3}×2^{8}=2^{8}

3^{2}×4^{2}=(12)^{4}

3^{8} ÷ 3^{5}=3^{-2}

7^{20} ÷ 7^{14}=7^{6}

9^{3}÷18^{6}=(\;\;{1}/{2})^{3}

On the basis of this response sheet Mr. Sharma can make the following observations :

Child has understood the laws of exponents and can apply them well.
Child has understood the laws of exponents but has made clerical errors.
Child has understood the laws of exponents but has not practised the questions involving division of two numbers.
Child has understood the law of exponents for the cases where the base is same and has missed the concept for the case where the base is different.
