The value of 27^(1/3) is:
सही उत्तर: ग) 3
27^(1/3) is the cube root of 27, and 3 × 3 × 3 = 27. 9 would be 27^(2/3).

a⁻ⁿ (a ≠ 0) is equal to:
सही उत्तर: ग) 1/aⁿ
A negative index means the reciprocal: a⁻ⁿ = 1/aⁿ. It does not make the value negative.

(aᵐ)ⁿ is equal to:
सही उत्तर: घ) aᵐⁿ
Raising a power to another power multiplies the indices: (aᵐ)ⁿ = aᵐⁿ. Adding indices applies only to multiplying powers with the same base.

According to the laws of indices, aᵐ × aⁿ equals:
सही उत्तर: क) aᵐ⁺ⁿ
When multiplying powers of the same base, the indices are added: aᵐ × aⁿ = aᵐ⁺ⁿ. The product aᵐⁿ comes from (aᵐ)ⁿ, a power of a power.

The value of any non-zero number raised to the power 0 is:
सही उत्तर: ख) 1
By the law of indices, a⁰ = 1 for any a ≠ 0. This follows from aᵐ ÷ aᵐ = aᵐ⁻ᵐ = a⁰ = 1.

Which of the following is an irrational number?
सही उत्तर: ख) √2
√2 cannot be expressed as a ratio of two integers and its decimal neither terminates nor repeats. 22/7 is only a rational approximation of π, so it is rational.

A number that can be written in the form p/q, where p and q are integers and q ≠ 0, is called a:
सही उत्तर: ग) Rational number
Rational numbers can be expressed as p/q with integer p, q and q ≠ 0. Irrational numbers such as √2 cannot be written in this form.

-
Which of the following is the smallest prime number?
सही उत्तर: घ) 2
2 is the smallest prime and the only even prime. 1 is not prime because it has only one factor.

-
A number that has exactly two distinct factors, 1 and itself, is called a:
सही उत्तर: क) Prime number
A prime number has exactly two factors: 1 and the number itself. A composite number has more than two factors; 1 is neither prime nor composite.
