化简 \sqrt[3]{56r^8s^4}

解答

化简

3 56 r^{8} s^{4}

237 r^{2} s 3 r^{2} 3 s

求解步骤

3 56 r^{8} s^{4}

3 56 r^{8} s^{4} = 356 3 r^{8} 3 s^{4}

= 356 3 r^{8} 3 s^{4}

化简

3 r^{8} : r^{2} 3 r^{2}

= 356 r^{2} 3 r^{2} 3 s^{4}

化简

3 s^{4} : s 3 s

= 356 r^{2} 3 r^{2} s 3 s

356 = 237

= 237 r^{2} 3 r^{2} s 3 s

= 237 r^{2} s 3 r^{2} 3 s
