Số lượng thừa số 2 trong A là 2020, và số lượng thừa số 5 trong A cũng là 2020. Ta có thể viết lại A dưới dạng tích của 2^2020 và 5^2020:
A = 2^2020 × 5^2020
Để tính giá trị của A, ta có thể sử dụng máy tính hoặc sử dụng tính chất a^b × a^c = a^(b+c) để rút gọn biểu thức:
A = 2^2020 × 5^2020
= (2^2)^1010 × (5^2)^1010
= 4^1010 × 25^1010
= (2^2 × 5^2)^1010
= 10^4040
Vậy A = 10^4040
A=2×2×2×2×...×2×5×5×5×...×5.
A=(2x5)x(2x5)x...x(2x5) (2020 cặp)
A=10x10x...x10 (2020 số 10)
A= 102020.
Số to lắm ấy nhé
A=2*2*2*2*...*2*5*5*5*5...*5
A=22020+52020
A = 83063219225094000583421664188183520277586972643903623739657337470038307699263261926505458362577322779327050086760092932092707656593211520434215458150129669772162538931944821533658114656352133024674020421428416702181158419582090601095015222944399840624201705680035013901291762810494771870077412336904126353160012685514155928651480205209321687573270460760578090096562076336561740954386196805999585126551045488869396897421691770488455454550501032508486518355703414840111891946335474670284115248208705250049169281248504564307639391897795918914060426708477712788226072417741679994208296566096202905592886851953212149367089109267918862896278158866460776662259360515125982439975467297074916849604032072548538950509591429407637995271267454950742098056035365594621661046837954187037184419525760098872802898926807373850678517240716308816922608745349459900403418055873857730946582911425841420706139343365054923107471073593371920983857313521298750691101429204230758155637041792164832931632523855018395791110888327083155712413035337201875146003473989178045589783220103304740584322940020829181326966536323427039515742447171325973996086722857629524256831812706489669501364034807629183610498353702268718741571953176285899927052089499946775282710795377563152568218892123795879167841039203798891931001399680279620001698193096941443532693370804050104352457150705454883607543622881789636430289912961628464916762717620259358933609201337470038307699263261926505458362577322779327050086760092932092707656593211520434215458150129669772162538931944821533658114656352133024674020421428416702181158419582090601095015222944399840624201705680035013901291762810494771870077412336904126353160012685514155928651480205209321687573270460760578090096562076336561740954386196805999585126551045488869396897421691770488455454550501032508486518355703414840111891946335474670284115248208705250049169281248504564307639391897795918914060426708477712788226072417741679994208296566096202905592886851953212149367089109267918862896278158866460776662259360515125982439975467297074916849604032072548538950509591429407637995271267454950742098056035365594621661046837954187037184419525760098872802898926807373850678517240716308816922608745349459900403418055873857730946582911425841420706139343365054923107471073593371920983857313521298750691101429204230758155637041792164832931632523855018395791110888327083155712413035337201875146003473989178045589783220103304740584322940020829181326966536323427039515742447171325973996086722857629524256831812706489669501364034807629183610498353702268718741571953176285899927052089499946775282710795377563152568218892123795879167841039203798891931001399680279620001698193096941443532693370804050104352457150705454883607543622881789636430289912961628464916762717620259358933609201
