238.39.340が全く分かりません。 やり方を教えてください

2進法で表すと10桁である自然数Nがある。この自然数を4進法で表すと何桁の数に 数学と人間の活動 156 例題 18 なるか。 (考え方)か進法で表したとき, れ桁の自然数Nは が'SN<がと表せる。 解答 自然数 Nは 2°<N<2° の範囲にある。 2°=2-2°=2-(2°)=2·4° 4進法に直すために 2°と 20をa-4"の形で表す。 20=(2°)=4 であるから 2-4'SN<4° 100T よって、Nを4進法で表すと5桁の数である。 別解 2進法で表すと10桁である自然数のうち, 最小の数を10進法で表すと 1000000000(2) =2°=512 2進法で表すと10桁である自然数のうち,最大の数を10進法で表すと 1111111111 (2)=10000000000 (2)一1(2=2"-1=1023 よって 512NS1023 ここで 512=20000 (4) 1023=33333 () であるから 20000 ()SN<33333 (4) ゆえに, Nを4進法で表すと5桁の数である。 | 238 3進法で表すと 12桁である自然数Nを, 9進法で表すと何桁の数になるか。 | 239 自然数のうち, 10進法で表しても6進法で表しても,3桁になるものは全部で何個 口220 あるか。 例題 19 10進法で表された2桁の自然数Nを4進法で表したところ,数字の並びが反対の順に なった。この自然数を10進法で表せ。 (考え方) Nを10 進法で10a+bと表すと, 4進法では baw=46+aと表せる。 解答 Nを10進法で表したとき, 10の位の数を a, 1の位の数をbとすると 4進法で表すとba wであるから N=10a+b=4b+a (ただし, 1<aい3, 1<b<3 ………0) よって, 9a=36より 3a=b のの範囲でこれを満たすのは a=1, b=3 ゆえに N=10.1+3=13 になった。この自然数を10進法で表せ。
