2 ⊕ 5 = \text{2}{\oplus}{5}= (2×2=4)+(4×5=20) = 24 \text{(2×2=4)+(4×5=20) = 24}

∴ \therefore the answer is 24 \color{#302B94}{24}

2a + 4b = 2(2) + 4(5)= 4 + 20= 24

a ⊕ b = 2 a + 4 b a\oplus b=2a+4b

From the problem, a = 2 a=2 and b = 5 b=5 , substitute

2 ⊕ 5 = 2 ( 2 ) + 4 ( 5 ) = 4 + 20 = 24 2\oplus 5=2(2)+4(5)=4+20=\boxed{24}
