(3乘10的3次方)的2次方除以(5乘10的4次方)
问题描述:
(3乘10的3次方)的2次方除以(5乘10的4次方)
答
(3*10³)²/(5*10)^4=(3² * 10^6)/(5^4 *10^4)
=9 * 10²/5^4
=36/25
答
(3*10³)²/(5*10)^4=(3² * 10^6)/(5^4 *10^4)
=9 * 10²/5^4=36/25
答
(3乘10的3次方)的2次方除以(5乘10的4次方)
=(3的2次方)×(10的3次方的2次方)÷50000
=(3的2次方)×(10的6次方)÷50000
=9×10000000÷50000
=1800
=1.85×10³
