This question is from the book: C*-algebras and Finite-Dimensional Approximations by N.P.Brown and N. Ozawa Ex 13.3.5.
Let C$_i$ (i=1,2) be C*-algebras with the LLP and J$_i$ be a closed two-sided ideal in C$_i$. Prove that if A$_1$ = C$_1$/J$_1$ is QWEP, then
A$_1$ $\otimes$$_{max}$ A$_2$ = C$_1$$\otimes$C$_2$/(J$_1$$\otimes$C$_2$ + C$_1$$\otimes$J$_2$）
canonically. Here $\otimes$ means minimal tensor product.
