化简 \sqrt[4]{8x^2}*\sqrt[4]{2x^2}

解答

化简

4 8 x^{2} \cdot 4 2 x^{2}

2 (4 x^{2})^{2}

求解步骤

4 8 x^{2} 4 2 x^{2}

化简

4 8 x^{2} : 48 4 x^{2}

= 48 4 x^{2} 4 2 x^{2}

化简

4 2 x^{2} : 42 4 x^{2}

= 48 4 x^{2} 42 4 x^{2}

4842 = 416

= 416 4 x^{2} 4 x^{2}

416 = 2

= 2 4 x^{2} 4 x^{2}

使用指数法则:

aa = a^{2}

4 x^{2} 4 x^{2} = (4 x^{2})^{2}

= 2 (4 x^{2})^{2}
