3. Answer the following questions in about 120 words.
(i) Explain the land use pattern in India and why has the land under forest not increased much since 1960-61.
Answer:
The use of land is determined both by physical factors, such as topography, climate, and soil types, as well as by human factors, such as population density, technological capability, culture, traditions etc. The pattern of the net sown area varies greatly from one state to another. It is over 80 per cent of the total area in Punjab and Haryana and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and Andaman Nicobar Islands. Forest area in the country is far lower than the desired 33 per cent of the geographical area, as it was outlined in the National Forest Policy (1952). It was considered essential for the maintenance of the ecological balance. A part of the land is termed a wasteland, and it is put to other non-agricultural uses like settlements, roads, railways, industry etc. It includes rocky, arid and desert areas. Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it has resulted in land degradation.
(ii) How has technical and economic development led to more consumption of resources?
Answer:
There are various reasons for this.
The students will get to know about the following topics:

Chapter 1 of the RD Sharma textbook provides us with the knowledge of Number Systems, including rational and irrational numbers, representing the numbers on a number line, real numbers, rationalisation and laws of exponents. Shortcut methods and tricks are provided, which include formulas that are used in solving chapter-wise problems, as per the latest CBSE syllabus.
The exercise-wise solution links covered in this chapter are provided below.
Chapter 2 of the RD Sharma textbook contains problems based on important topics like Integral Exponents of a Real Number, Laws of Integral Exponents, and Rational Exponents of a Real Number. These topics are explained by experts according to the understanding level of students.
1. Product with same bases: As per this law, for any non-zero term a,
a^{m}×a^{n }= a^{m+n}
Where m and n are real numbers.
2. Quotient with same bases: As per this rule,
a^{m}/a^{n} = a^{m-n}
Where a is a non-zero term and m and n are integers.
3. Power raised to a power: According to this law, if ‘a’ is the base, then the power raised to the power of base ‘a’ gives the product of the powers raised to the base ‘a’, such as
(a^{m})^{n} = a^{mn}
Where a is a non-zero term and m and n are integers.
4. Product to a power: As per this rule, for two or more different bases, if the power is the same, then
a^{n }b^{n }= (ab)^{n}
Where a is a non-zero term and n is the integer.
5. Quotient to a power: As per this law, the fraction of two different bases with the same power is represented as
a^{n}/b^{n }= (a/b)^{n}
Where a and b are non-zero terms and n is an integer.
6. Zero Power: According to this rule, when the power of any integer is zero, then its value is equal to 1, such as;
a^{0 }= 1
where ‘a’ is any non-zero term.
7. Negative Exponent Rule: According to this rule, if the exponent is negative, we can change the exponent into positive by writing the same value in the denominator, and the numerator holds the value 1.
The negative exponent rule is given as
a^{-m} = 1/a^{m}
8. Fractional Exponent Rule: The fractional exponent rule is used, if the exponent is in the fractional form. The fractional exponent rule is given by
a^{1/n} =��
