Answer 1

\(60=2^{^2}.3.5\)

\(84=2^2.3.7\)

\(1035=3^{^2}.5.23\)

\(10000=2^{^4}.5^{^4}\)

\(225=3^{^2}.5^{^2}\)

\(1800=2^{^3}.3^{^2}.5^{^2}\)

\(1050=2.3.5^{^2}.7\)

\(3060=2^{^2}.3^{^2}.5.17\)

Answer 2

ta có :

`a) 60 = 2^2 . 3.5`

`b) 84 = 2^2 . 3. 7`

`c) 1035 = 3^2 . 5 . 23`

`e) 10 000 = 2^4 . 5^4`
`j)225 = 3^2 . 5^2`
`g)1800 = 2^3 . 3^2 . 5^2`
`h)1050 = 2 . 3 . 5^2 . 7`
`i)3060 = 2^2 . 3^2 . 5 . 17`
