Question

So sánh 199^20 và 2003^15

Answer 1

ta có:

\(199^{20}=\left(199^4\right)^5=1568239201^5\)

\(2003^{15}=\left(2003^3\right)^5=8036054027^5\)

vì \(1568239201>1\)

    \(8036054027>1\)

\(1568239201< 8036054027\)

=>\(199^{20}< 2003^{15}\)

Answer 2

199²⁰=(199⁴)⁵=1568239201⁵

2003¹⁵=(2003³)⁵=8036054027⁵

Vì 1568239201<8036054027

Vậy 199²⁰ <2003¹⁵

Answer 3

\(199^{20}< 2003^{15}\)
