Transcript
Ex 14.3, 3 Work out the following divisions. (iv) 9๐ฅ^2 ๐ฆ^2(3z โ 24) รท 27xy(z โ 8) We first factorise ใ9๐ฅใ^2 ๐ฆ^2 (3z โ 24) = ใ9๐ฅใ^2 ๐ฆ^2 ร [3z โ (3 ร 8)] Taking 3 common, = ใ9๐ฅใ^2 ๐ฆ^2 ร 3 (z โ 8) = 27 ๐ฅ^2 ๐ฆ^2 (z โ 8) Dividing, (9๐ฅ^2 ๐ฆ^2 (3๐ง โ 24))/(27๐ฅ๐ฆ (๐ง โ 8)) = (27๐ฅ^2 ๐ฆ^2 (๐ง โ 8))/(27๐ฅ๐ฆ (๐ง โ 8)) = 27/27 ร ๐ฅ^2/๐ฅ ร ๐ฆ^2/๐ฆ ร ((๐ง โ 8))/((๐ง โ 8)) = 1 ร x ร y ร 1 = xy (๐ด๐ ๐^๐/๐^๐ =๐^(๐ โ n) )
