Example 3 Using exponents, express the prime factorisation of the following (a) 500 (b)

- \frac{1}{243}

\frac{- 27}{343}

(d) 400 Solution (a)

500 = (2 \times 2) \times (5 \times 5 \times 5) = 2 \times 5

- \frac{1}{243} = \frac{- 1}{243} = \frac{- 1 \times- 1 x - 1 \times- 1 x - 1}{3 \times 3 \times 3 \times 3 \times 3} = \frac{( - 1 ) ^{5}}{3 ^{5}} = (\frac{1}{3})^{5}

\frac{- 27}{343} = \frac{( - 3 ) \times ( - 3 ) \times ( - 3 )}{7 \times 7 \times 7} = \frac{( - 3 ) ^{3}}{7 ^{3}} = (\frac{- 3}{7})^{3}

(d) Working 2,8

400 = (5 \times 5) \times 2 \times 2 \times 2 \times 2 = 5^{2} \times 2^{4}

When Ali jumped into cold water, he realised that he was able to hold his breathe longer in water as compared to when he was out of water. Ali found that when he is cold water, his blood vessels contacts. How did the contracting of blood vessels help him to hold his breathe longer in cold water?

less carbon dioxide will be utilised by the body
more blood rich in oxygen will be pumped by the heart
More carbon dioxide will be conserved by the body
less blood rich in oxygen will reach all parts of the body
