Correct Answer: D. 2

Explanation

\(\frac{\log_{5} 8}{\log_{5} \sqrt{8}} = \frac{\log_{5} 8}{\log_{5} 8^{\frac{1}{2}}}\)

= \(\frac{\log_{5} 8}{\frac{1}{2}\log_{5} 8}\)

= \(\frac{1}{\frac{1}{2}} \)

= 2

Correct Answer: D) sulphur (IV) oxide

Correct Answer: C. Gamma rays

Explanation

(a) Balance of trade = visible exports - visible imports

= $200.00 + $300.00

= $ 500.00 million

Visible imports = $250.00 - $650.00

= - $150.00million

(b) Invisible trade balance = inviible exxports - invisible im ports

Invisible exports = $25.00 + $30.00 + $25 = $80.00 million

Invisible imports = $50.00 + $75.00 + $85.00 = $210.00 million

Invisible = $80.00 - $210.00 = -$130.00

(c) Balance on current account = balance of trade + invisble trade balance

= $150.00 +($130.00)

= $150.00 + $130

= $ 280.00

OR

Total exports - total imports

= $(200 + 300 + 25 + 30 + 25) - $(250 + 400 + 50 + 75 + 85)

= $580 - $860 = - $280
