若(a-1/3)²+1/5|b-2|+6(1-c)²=0求(-bc²)²*(3/4ac)³/(3/2ac²)³的值若(a-1/3)
若(a-1/3)²+1/5 |b-2|+6(1-c)²=0求(-bc²)²*(3/4ac)³/(3/2ac²)³的值
若(a-1/3)²+1/5 |b-2|+6(1-c)²=0
求(-bc²)²*(3/4ac)³/(3/2ac²)³的值
若(a-1/3)²+1/5 |b-2|+6(1-c)²=0求(-bc²)²*(3/4ac)³/(3/2ac²)³的值
(a-1/3)²+(1/5) |b-2|+6(1-c)²=0,
∴a=1/3,b=2,c=1.
原式=4*9³/(9/2)³
=4*8
=32
(a-1/3)²+(1/5) |b-2|+6(1-c)²=0,
∴a=1/3,b=2,c=1.
原式=b^c^4*(27/64)a^3c^3*(27/8)a^3c^6
=(729/512)a^6b^c^13
=(729/512)(1/3)^6*2^
=1/128.
=>a=1,b=2,c=1(-bc^2)^2*(3ac/4)^3/(3ac^2)^3=4*(27/81)/(27/8)=32/81
