Question

1/4+2.25-0.25+7.75(脱式计算

Answer 1

1/4+2.25-0.25+7.75(脱式计算

1/4+2.25-0.25+7.75
=0.25+2.25-0.25+7.75
=（0.25-0.25）+（2.25+7.75）
=0+10
=10

脱式计算1/[0.25-(1-0.85)]

等于1/【0.25-0.15】
等于1/0.1
等于10

[(0.75+1又1/2)÷0.25-4/7]*3.5的脱式计算

[(0.75+1又1/2)÷0.25-4/7]*3.5
=[(0.75+1又1/2)×4-4/7]*3.5
=[0.75×4+1又1/2×4-4/7]*3.5
=[3+6-4/7]*3.5
=59/7×7/2
=59/2

2.25÷0.25x4脱式计算

2.25÷0.25x4
=5x4
=20

7.75+2.25 2.5x40脱式计算

7.75+2.25 2.5x40脱式计算
7.75+2.25 +2.5x40
=10+100
=110

0.25÷[(1/3 0.4)x5/22]脱式计算

0.25÷[(1/3 +0.4)x5/22]
=1/4÷【（1/3+2/5）x5/22】
=1/4÷（11/5x5/22）
=1/4÷1/2
=1/2

0.25×36+25%乘74-1/4×4脱式计算

原式=0.25×36+0.25×74-0.25×4
=0.25×（36+74-4）
=0.25×106
=0.25×（100+6）
=0.25×100+0.25×6
=25+1.5
=26.5

计算(1/4)∧一(1/27)∧-1/3-625∧0.25=?

你好 (1/4)∧ 这里是几次方啊？我假设是-2次方吧
(1/4)^-2一(1/27)∧-1/3-625∧0.25
=16-[3^(-3)]^1/3-(5^4)^0.25
=16 -1/3-5
=11-1/3
=32/3

-9×(-1/4)+0.25×25.5-11/2×(-0.25)计算

-9×(-1/4)+0.25×25.5-11/2×(-0.25)
=9×0.25+0.25×25.5+5.5×0.25
=0.25×（9+25.5+5.5）
=0.25×40
=10
