Ex 9.5, 3 Find the following squares by using the identities. (iv) (2/3 π‘š+3/2 𝑛)^2 (2/3 π‘š+3/2 𝑛)^2 (π‘Ž+𝑏)^2=π‘Ž^2+𝑏^2+2π‘Žπ‘ Putting π‘Ž = 2/3 π‘š & 𝑏 = 3/2 𝑛 = (2/3 π‘š)^2+(3/2 𝑛)^2+2(2/3 π‘š)(3/2 𝑛) = (2/3)^2Γ—π‘š^2+(3/2)^2×𝑛^2+((2 Γ— 2 Γ— 3)/(3 Γ— 2))Γ—(π‘šΓ—π‘›) = πŸ’/πŸ— π’Ž^𝟐+ πŸ—/πŸ’ 𝒏^𝟐+πŸπ’Žπ’
