Correct Answer: B. educating farmers on the use of improved inputs and techniques in agriculture

Explanation

(a) \((\sqrt{3} - 5\sqrt{2})(\sqrt{3} + \sqrt{2}) = \sqrt{3 \times 3} + \sqrt{3 \times 2} - 5\sqrt{2 \times 3} - 5\sqrt{2 \times 2}\)

= \(3 + \sqrt{6} - 5\sqrt{6} - 5(2)\)

= \(-7 - 4\sqrt{6}\)

\(\therefore\) a = -7 and b = -4.

(b) \(\frac{2^{1 - y} \times 2^{y - 1}}{2^{y + 2}} = 8^{2 - 3y}\)

\(\frac{2^{1 - y + y - 1}}{2^{y + 2}} = (2^{3})^{2 - 3y}\)

\(2^{0 - (y + 2)} = 2^{6 - 9y} \implies 2^{- y - 2} = 2^{6 - 9y}\)

\(- y - 2 = 6 - 9y \implies - y + 9y = 6 + 2\)

\(8y = 8 \implies y = 1\).

Correct Answer: C. \(1311_5\)

Explanation

\(413_7\) to base 5

convert first to base 10

\(417_7 = 4 × 7^2 + 1 × 7^1 + 3 × 7^0\)

= 4 × 49 + 1 × 7 + 3 × 1

= 196 + 7 + 3

= \(206_{10}\)

convert this result to base 5

\(∴ 413_7 = 1311_5\)

Correct Answer: B. 6
