Answer:
[tex]280000[/tex]
Step-by-step explanation:
Given the following question:
[tex]7372\times39[/tex]
To estimate by rounding each number so it only has one nonzero digit, we have to round the number that is the furthest on the left.
[tex]7372\times39[/tex]
[tex]7372[/tex]
[tex]3<5[/tex]
[tex]7000[/tex]
[tex]39[/tex]
[tex]9>5[/tex]
[tex]40[/tex]
[tex]7000\times40=280000[/tex]
[tex]=280000[/tex]
Hope this helps.
