1/3-1/7-1/13/2/3-2/7-2/3×3/4-3/16-3/64/1-1/4-1/16-1/64+5/8

tính

( 1/3 - 1/7 - 1/13 ) / ( 2/3 - 2/7 - 2/13 ) x ( 3/4 - 3/16 - 3/64 - 3/256 ) / ( 1- 1/4 - 1/16 - 1/64 )  + 5/8

thu gọn:

a)        (2+1)(2^2+1)(2^4+1)..............(2^32+1)-2^64

b)         (5+3)(5^2+3^2)(5^4+3^4)...................(5^64+3^64).\(\frac{5^{128}-3^{128}}{2}\)

\(\left(\dfrac{1}{64}-\dfrac{1}{3^2}\right).\left(\dfrac{1}{64}-\dfrac{1}{4^2}\right).\left(\dfrac{1}{64}-\dfrac{1}{5^2}\right)...\left(\dfrac{1}{64}-\dfrac{1}{64^2}\right)\)

\(\frac{\frac{1}{3}-\frac{1}{7}-\frac{1}{13}}{\frac{2}{3}-\frac{2}{7}-\frac{2}{13}}\times\frac{\frac{3}{4}-\frac{2}{16}-\frac{3}{64}-\frac{3}{264}}{1-\frac{1}{4}-\frac{1}{16}-\frac{1}{64}}\)

tính giá trị của biểu thức sau

a, 1/3-1/7-1/7 /2/3-2/7-2/13 ✖3/4-3/16-3/64-3/256 / 1-1/4-1/16-1/64 +5/8

a) A=(2+1)(2²+1)(2⁴+1)...(2⁶⁴+1)+1

b)B=(3+1)(3²+1)(3⁴+1)...(3⁶⁴+1)+1

c)C=(a+b+c)²+(a+b-c)²-2(a+b)²

a) A=(2+1)(2²+1)(2⁴+1)...(2⁶⁴+1)+1

b)B=(3+1)(3²+1)(3⁴+1)...(3⁶⁴+1)+1

c)C=(a+b+c)²+(a+b-c)²-2(a+b)²

3(2^2+1)(2^4+1)..(2^64+1)+1=
