若x^2n=6,则3(x^2)2n=_________?
若x^2n=6,则3(x^2)2n=_________?
若x^2n=6,则3(x^2)2n=_________?
题目是不是这样的3(x^2)^(2n)
因为x^2n=6
所以原式3(x^2n)^2=3*6^2=108
3(x^2)2n
=3x^(2*2n)
=3x^(2n)^2
=3*6^2
=3*36
=108
3(x^2)^2n=3x^(2×2n)=3[x^(2n)]^2=3×6^2=108
3(x^2)2n
=3x^(2*2n)
=3x^(2n)^2
=3*6^2
=3*36
=108
108
3(x^2)^2n=3(x^2n)^2=3*6^2=3*36=108
