Question 1: Write (625)^–1/4 in decimal form.

Solution:

(625)^–1/4 = (5⁴)^-1/4 = 5^-1 = 1/5 = 0.2

Question 2: State the product law of exponents:

Solution:

To multiply two parts having same base, add the exponents.

Mathematically: x^m x xⁿ = x^{m +n}

Question 3: State the quotient law of exponents.

Solution:

To divide two exponents with the same base, subtract the powers.

Mathematically: x^m ÷ xⁿ = x^{m – n}

Question 4: State the power law of exponents.

Solution:

Power law of exponents :

(x^m)ⁿ = x^{m x n} = x^mn

Question 5: For any positive real number x, find the value of

Solution:

Question 6: Write the value of {5(8^1/3 + 27^1/3 ) ³}^1/4 .

Solution:

{5(8^1/3 + 27^1/3 ) ³}^1/4

= {5(2^3×1/3 + 3^3×1/3 ) ³}^1/4

= { 5(2 + 3)^3}^1/4

= (5⁴ ) ^1/4

= 5
