Question

I don’t get this question, please help.

Answer 1

A = 7

B = 2

Explanation:

The question is asking for the simplified form of √(-98). You are expected to know that √-1 = i, and you are expected to be able to factor the number 98.

`√(-98)=√((-1)(7^2)(2))=7i√(2)`

Matching parts of the simplified expression to the form you are given, you see that ...

A = 7

B = 2
