根号63*根号28/【4根号2+(-3根号2)】
根号48*根号18+根号12*根号16
我要过程
=(9√ 2+7√ 2)*√ 3/2
=16√ 2*√ 3/2
=16√ 3
根号63*根号28/【4根号2+(-3根号2)】
=3√7*2√7/√2
=6*7/√2
=21√2
根号48*根号18+根号12*根号16
=4√3*3√2+2√3*4
=12√6+8√3
=[根号(81×3)+根号(49×2]*根号2分之3
=(9倍根号3+7倍根号2)*3/2倍根号3
=81/2+21/2倍根号6
根号63*根号28/【4根号2+(-3根号2)】
=3倍根号7*2倍根号7÷(根号2)
=42÷根号2
=21倍根号2
根号48*根号18+根号12*根号16
=4倍根号3*3倍根号2+2倍根号3*4
=12倍根号6+8倍根号3
