Answer:
`\textsf{ab} > \textsf{0}`

-------------------------------------------------------------------------------------------------------------

Given:
`\textsf{a} > \textsf{0 and b} > \textsf{0}`

Find:
`\textsf{ab } \_\_\_ \textsf{ 0}`

Solution: Since we know both a and b are positive this means that if they are multiplied against each other they would produce another positive. Therefore, this would cause the statement to be ab > 0.
