\(63^{15}< 64^{15}=\left(2^6\right)^{15}=2^{6.15}=2^{90}\)
\(34^{18}>32^{18}=\left(2^5\right)^{18}=2^{5.18}=2^{90}\)
Vậy \(63^{15}< 34^{18}\)
6315 = 633.5 = (635)3 = 9924365433
3418 = 343.6 = (346)3 = 21767823363
=> 6315 <3418
\(34^{18}>32^{18}=2^{90}=64^{15}>63^{15}\)
Ta có \(63^{15}=63^{3.5}=\left(63^5\right)^3=250047^3\)
\(34^{18}=\left(34^6\right)^3=1544804416^3\)
Vậy\(63^{15}< 34^{18}\)
Mình làm số hơi lớn nha!
