题目不太清楚,按我理解的做.
1.√(x⁵ + x⁴y²) = √[x⁴(x + y²) = x²√(x + y²)
2.√[4x²y⁴*3xy) = 2xy²√(3xy)
3.√(2/3)*√54 = √(2*54/3) = √36 = 6
4.√(1/7)*√56 = √(1*56/7) = √8 = 2√2
5.√a*√(a³b²) = √(a⁴b²) = a²b
6.√(a/2)*√(4a²) = √(2a³) = a√(2a)
7.√a³*√(ab) = √(a⁴b) = a²b
8.2v(6xy)*(-1/4)√(32xy²) = -2*(1/4)*4*v(6xy)*√(2xy²)= -2√(12x²y³) = -4xy√(3y)

你的邮箱告诉我,我给你发到邮箱去

你这是解方程,还是求定义域,或其他什么啊?
