If u get it right... u get... pts!!...​

Answer 1

155.

Explanation:

By the definition of a square root the answer is 155.

Answer 2

155

Explanation:

Solution

`√(155) *√(155)` is the same thing as
`√(155)^2`, when we square a square root, we get the number that's inside the radical.

• E.g.
  `√(x) ^2` would get us x as the answer.

Given this method, we can easily say that
`√(155) * √(155)` is just
`155`.

Another way:

• Let's take the number 16 as an example.
• The square root of 16 is four, so we can put it as:
  `√(16) * √(16) =16`, or
  `4*4=16`.
• This same method applies to the problem, so again, we can say the answer is 155.
