Ex 9.4, 3 Simplify. (ii) (๐^2+5) (๐^3+3)+5 Here, there are 2 expressions: 1st expression = (๐^2+5) (๐^3+3) 2nd expression = 5 Solving 1st expression (๐^2+5) (๐^3+3) = ๐^2 (๐^3+3)+5(๐^3+3) = (๐^2ร๐^3 )+(๐^2ร3)+(5ร๐^3 )+(5ร3) = ๐^2 ๐^3+3๐^2+5๐^3+15 Now, our expression is (๐^2+5) (๐^3+3)+5 = ๐^2 ๐^3+3๐^2+5๐^3+15+5 = ๐^๐ ๐^๐+๐๐^๐+๐๐^๐+๐๐
