简便计算3.7654²+0.4692×3.7654+0.2346²,要过程
3.7654²+0.4692×3.7654+0.2346²
=(3.7654+0.2346)²
=4*4
=16

3.7654²+0.4692×3.7654+0.2346²
=3.7654²+2×0.2346×3.7654+0.2346²
=(3.7654+0.2346)^2
=4^2
=16

3.7654²+0.4692×3.7654+0.2346²
=（3.7654+0.2346）^2
=4^2
=16

3.7654²+0.4692×3.7654+0.2346²
=3.7654²+2×0.2346×3.7654+0.2346²
=(3.7654+0.2346)²
=4²
=16
