Correct Answer

A. (35)

Step 1

Concept

\(\sqrt{45}=3\sqrt{5}\) and \(\sqrt{80}=4\sqrt{5}\), so the bracket is \(7\sqrt{5}\) and the product is (35). Simplify the bracket first.

Step 2

Why this answer is correct

The correct answer is A. (35). \(\sqrt{45}=3\sqrt{5}\) and \(\sqrt{80}=4\sqrt{5}\), so the bracket is \(7\sqrt{5}\) and the product is (35). Simplify the bracket first.

Step 3

Exam Tip

\(\sqrt{45}=3\sqrt{5}\) और \(\sqrt{80}=4\sqrt{5}\), इसलिए कोष्ठक \(7\sqrt{5}\) और गुणनफल (35) है। पहले कोष्ठक सरल करें।
