0.4x(1+㎡)0.5
亲,化简过程如下:0.4x(1+㎡)0.5=0.4×0.5×(1+㎡)=0.2×(1+m²)=0.2+0.2m²
是0.4x(1+㎡)的0.5次方
亲,化简过程如下:0.4x(1+㎡)^0.5=0.4×(1+㎡)^1/2=0.2×√(1+m²)=√(0.04+0.04m²)
亲,化简过程如下:0.4x(1+㎡)^0.5=0.4×(1+㎡)^1/2=0.4×√(1+m²)=√(0.16+0.16m²)
亲,化简过程如下:0.4x(1+㎡)^0.5=0.16^0.5×(1+㎡)^0.5=(0.16×(1+m²))^0.5=(0.16+0.16m²)^0.5
亲,本题遵循:1.同底数幂相乘,底数不变,指数相加。2. 幂的乘方,底数不变,指数相乘。3. 积的乘方,等于把积的每一个因式分别乘方,再把所得的幂相乘。4.分式乘方, 分子分母各自乘方。
0.4×(1+4.02²)^0.5=0.4×(1+16.1604)^0.5=0.4×17.1604^0.5≈0.4×4.1425≈1.657
