This transfer is possible in two ways: direct transfer and using the decimal system.
first, let\'s make a direct transfer.
let\'s do a direct translation from octal to binary like this:
010101010011101010018 = 0 1 0 1 0 1 0 1 0 0 1 1 1 0 1 0 1 0 0 1 = 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 0(=000) 1(=001) 1(=001) 1(=001) 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 0(=000) 1(=001) = 0000010000010000010000010000000010010010000010000010000000012
answer: 010101010011101010018 = 10000010000010000010000000010010010000010000010000000012
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
0∙819+1∙818+0∙817+1∙816+0∙815+1∙814+0∙813+1∙812+0∙811+0∙810+1∙89+1∙88+1∙87+0∙86+1∙85+0∙84+1∙83+0∙82+0∙81+1∙80 = 0∙144115188075855872+1∙18014398509481984+0∙2251799813685248+1∙281474976710656+0∙35184372088832+1∙4398046511104+0∙549755813888+1∙68719476736+0∙8589934592+0∙1073741824+1∙134217728+1∙16777216+1∙2097152+0∙262144+1∙32768+0∙4096+1∙512+0∙64+0∙8+1∙1 = 0+18014398509481984+0+281474976710656+0+4398046511104+0+68719476736+0+0+134217728+16777216+2097152+0+32768+0+512+0+0+1 = 1830034040530585710
got It: 010101010011101010018 =1830034040530585710
