Answer 1

21
`e^(6)` and 30
`t^(6)`
`v^(10)`

Explanation:

using the rule of exponents

•
`a^(m)` ×
`a^(n)` =
`a^((m+n))`

given

3e³ × 7e³

= 3 × 7 × e³ × e³

= 21 ×
`e^((3+3))`

= 21
`e^(6)`

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

(10
`t^(4)`
`v^(5)` )(3t²
`v^(5)` )

= 10 × 3 ×
`t^(4)` × t² ×
`v^(5)` ×
`v^(5)`

= 30 ×
`t^((4+2))` ×
`v^((5+5))`

= 30
`t^(6)`
`v^(10)`
