几道计算题求速度
(1)-9×(-11)-96÷(-8)
(2)7-(3/8+1/6-3/4)×24
(3)-1的100次方-(1/6-2/5)÷1又3/4×[(-7)的平方-(-11)]
优质解答
(1)-9×(-11)-96÷(-8)
=99-(-12)
=99+12
=111
(2)7-(3/8+1/6-3/4)×24
=7-【(3/8)×24+(1/6)×24-(3/4)×24】
=7-(9+4-18)
=7-(-5)
=12
(3)-1的100次方-(1/6-2/5)÷1又3/4×[(-7)的平方-(-11)]
=1-【(1/6-2/5)×4/7】×【49+11】
=1-【(5/30-12/30)×4/7】×60
=1-【(-7/30)×4/7】×60
=1+8
=9
(1)-9×(-11)-96÷(-8)
=99-(-12)
=99+12
=111
(2)7-(3/8+1/6-3/4)×24
=7-【(3/8)×24+(1/6)×24-(3/4)×24】
=7-(9+4-18)
=7-(-5)
=12
(3)-1的100次方-(1/6-2/5)÷1又3/4×[(-7)的平方-(-11)]
=1-【(1/6-2/5)×4/7】×【49+11】
=1-【(5/30-12/30)×4/7】×60
=1-【(-7/30)×4/7】×60
=1+8
=9
