(8√[6]+3√[2])(4√[6]–5√[2]) = (8√6 * 4√6) - (8√6 * 5√2) + (3√2 * 4√6) - (3√2 * 5√2) = 192 - 80√3 + 24√3 - 30 = 162 - 56√3

while multiplying radicals, you're taking the fabricated from the constants in front f the radical, and multiply it via the fabricated from the radicals: (c1?x * c2?z) = (c1*c2)*(?x*z) while c1 and c2 are contants. (8?[6] + 3?[2])(4?[6] – 5?[2]) FOIL in basic terms such as you will possibly a typical binomial. You get: = 32?36 - 40?12 + 12?12 - 15?4 = 32*6 - 40?12 + 12?12 - 15*2 = 192 - 28?12 - 30 = 162 - 28?4*3 = 162 - fifty six?3
