化简 (20 18:41:34)
化简:根号140×根号35×π =(                                   )

化简 (20 18:41:34)化简:根号140×根号35×π =(                                &
根号140×根号35×π =(根号(35×4) 根号35×π == 根号35×根号4 根号35×π =根号35×根号35×根号4×π =(根号35×根号35)×根号4×π=35×2×π=70×π

TT根号140×35=70TT

根号140×根号35×π =根号(2×7×10×5×7)×π=根号(10×10×7×7)×π=70π
