Question

101+102+103+104+105+106+107+108+109рационально

Answer 1

(101+109)+(102+108)+(103+107+(104+106)+105=210+210+210+210+105=945

Answer 2

Rationally simplifying the expression: 101 + 102 + 103 + 104 + 105 + 106 + 107 + 108 + 109

We can group the numbers in pairs as follows: (101 + 109) + (102 + 108) + (103 + 107) + (104 + 106) + 105

Now, we can simplify each pair: 210 + 210 + 210 + 210 + 105

Finally, add all the simplified pairs together: 210 + 210 + 210 + 210 + 105 = 945

So, the rational simplification of the expression is 945.
