已知实数a,b满足√4a-b+11+√1/3b-4a-3=0求(√b/a÷√1/b)·2a√a/b的值已知实数a,b满足√4a-b+11+√1/3b-4a-3=0求(√b/a÷√1/b)·2a√a/b
已知实数a,b满足√4a-b+11+√1/3b-4a-3=0 求(√b/a÷√1/b)·2a√a/b的值
已知实数a,b满足√4a-b+11+√1/3b-4a-3=0 求(√b/a÷√1/b)·2a√a/b的值
已知实数a,b满足√4a-b+11+√1/3b-4a-3=0 求(√b/a÷√1/b)·2a√a/b的值
√4a-b+11+√1/3b-4a-3=0
∴4a-b+11=0
1/3b-4a-3=0
∴a=1/4
b=12
∴(√b/a÷√1/b)·2a√a/b
=√(b²/a) ×2a√(a/b)
=2a√b
=2×1/4×√12
=√3
