Rút gon phân thức:

A=(1^4+1/4).(3^4+1/4).(5^4+1/4)....(11^4+1/4) / (2^4+1/4).(4^4+1/4).(6^4+1/4)....(12^4+1/4) 

Tính giá trị của biểu thức

A= (1+1/4)(3^4 +1/4)(5^4 +1/4)...(29^4+1/4)/2^4+1/4)(4^4+1/4)(6^4+1/4)...(30^4+1/4)

1+1+1+1+1+1+1+1+1+1+1+11+11+1+1+1+1+1+1+1+11+0+0+0+0+0+4+4+4+4+4+4+4+4+4+4+4+4+4++4+4+44+0+0+0+++0+0++0+0++0+0+0++0 

kết quả bằng bao nhiêu?

đúng ghi Đ sai ghi S

a)1-3/4+1/4=1-3+1/4          b)1-3/4+1/4=4/4-3/4+1/4

                   =1-1=0[  ]                                1/4+1/4=1/2[  ]

tính A = (1^4 + 1/4 ).(3^4 +1/4)......(2019^4 + 1/4) / (2^4 + 1/4 ).(4^4 +1/4).......(2018^4 + 1/4)

Tính S= (2^4 + 1/4) (4^4 + 1/4).... (100^4+1/4) / (1^4+1/4) (3^4 +1/4) .... (99^4+1/4)

Tính giá trị biểu thức: A= (1+1/4)(3^4 +1/4)(5^4 + 1/4).....(29^4 +1/4) / (2^4 +1/4)(4^4 +1/4).......(30^4 +1/4)

Tính : \(\frac{\left(1^4+\frac{1}{4}\right)\left(3^4+\frac{1}{4}\right)\left(5^4+\frac{1}{4}\right)\left(7^4+\frac{1}{4}\right)\left(9^4+\frac{1}{4}\right)\left(11^4+\frac{1}{4}\right)}{\left(2^4+\frac{1}{4}\right)\left(4^4+\frac{1}{4}\right)\left(6^4+\frac{1}{4}\right)\left(8^4+\frac{1}{4}\right)\left(10^4+\frac{1}{4}\right)\left(12^4+\frac{1}{4}\right)}\)

Tính A/B

A=(1⁴+1/4)(3⁴+1/4)(5⁴+1/4)...........(19⁴+1/4)

B=(2⁴+1/4)(4⁴+1/4)(6⁴+1/4)...........(20⁴+1/4)

Tính A/B

A=(1⁴+1/4)(3⁴+1/4)(5⁴+1/4)...........(19⁴+1/4)

B=(2⁴+1/4)(4⁴+1/4)(6⁴+1/4)...........(20⁴+1/4)
