Question

Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 3ato the 3rd and 4ato the 3rd

Answer 1

Explanation:

`a^(2) + b ^(2) = c^(2)`

`[ (3a)^(3) ]^(2)` +
`[ (4a)^(3) ]^(2) = C^(2)`

I'm assuming the length was
`(3a)^(3)`, not 3
`a^(3)`.

It was difficult to tell in your question.

`(3a)^(6) +(4a)^(6) = C^(2)`

729
`a^(6)` + 4096
`a^(6) = C^(2)`

4825
`a^(6) = c^(2)`

Take the square root of both sides.

69.4622
`a^(3)` ≈ c
