(a) 5 hundreds x 10;
[tex]\begin{gathered} 500\times10 \\ =5,000 \end{gathered}[/tex]In standard form, it is 5,000

[tex]\begin{gathered} 50\text{ hundreds;} \\ OR \\ 5\text{ thousands+0 hundreds + 0 tens + 0 ones.} \end{gathered}[/tex](b) 10 x 3 tens;
[tex]10\times30=300[/tex]In standard form, it is 300
