\(\sqrt{32}+\sqrt{128}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{32}+\sqrt{128}\)?

Explanation opens after your attempt
Correct Answer

A. \(12\sqrt{2}\)

Step 1

Concept

\(\sqrt{32}=4\sqrt{2}\) and \(\sqrt{128}=8\sqrt{2}\).

Step 2

Why this answer is correct

\(4\sqrt{2}+8\sqrt{2}=12\sqrt{2}\).

Step 3

Exam Tip

Radicals can be added only when they become like radicals. चरण 1: \(\sqrt{32}=4\sqrt{2}\) और \(\sqrt{128}=8\sqrt{2}\)। चरण 2: \(4\sqrt{2}+8\sqrt{2}=12\sqrt{2}\)। चरण 3: समान वर्गमूल बनने पर ही उन्हें जोड़ा जा सकता है।

\(\sqrt{175}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{175}\)?

Explanation opens after your attempt
Correct Answer

C. \(5\sqrt{7}\)

Step 1

Concept

Write \(175=25 \times 7\).

Step 2

Why this answer is correct

\(\sqrt{175}=\sqrt{25 \times 7}=5\sqrt{7}\).

Step 3

Exam Tip

Take the perfect square factor outside and keep the remaining number inside. चरण 1: \(175=25 \times 7\) लिखें। चरण 2: \(\sqrt{175}=\sqrt{25 \times 7}=5\sqrt{7}\)। चरण 3: पूर्ण वर्ग गुणनखंड को बाहर और बाकी संख्या को अंदर रखें।

कौन-सा विकल्प \(\sqrt{24}\) का सरल रूप है?

Which option is the simplified form of \(\sqrt{24}\)?

Explanation opens after your attempt
Correct Answer

A. \(2\sqrt{6}\)

Step 1

Concept

\(24=4 \times 6\).

Step 2

Why this answer is correct

\(\sqrt{24}=\sqrt{4 \times 6}=2\sqrt{6}\).

Step 3

Exam Tip

If (6) remains inside, it cannot be simplified further because it has no perfect square factor. चरण 1: \(24=4 \times 6\) है। चरण 2: \(\sqrt{24}=\sqrt{4 \times 6}=2\sqrt{6}\)। चरण 3: यदि अंदर (6) बचे तो वह आगे सरल नहीं होगा क्योंकि (6) में पूर्ण वर्ग गुणनखंड नहीं है।

\(\sqrt{147}\) को सरल कीजिए।

Simplify \(\sqrt{147}\).

Explanation opens after your attempt
Correct Answer

A. \(7\sqrt{3}\)

Step 1

Concept

Write \(147=49 \times 3\).

Step 2

Why this answer is correct

\(\sqrt{147}=\sqrt{49 \times 3}=7\sqrt{3}\).

Step 3

Exam Tip

Recognising the perfect square (49) is the main step here. चरण 1: \(147=49 \times 3\) लिखें। चरण 2: \(\sqrt{147}=\sqrt{49 \times 3}=7\sqrt{3}\)। चरण 3: पूर्ण वर्ग (49) को पहचानना यहां मुख्य कदम है।

\(\sqrt{90}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{90}\)?

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{10}\)

Step 1

Concept

Write \(90=9 \times 10\).

Step 2

Why this answer is correct

\(\sqrt{90}=\sqrt{9 \times 10}=3\sqrt{10}\).

Step 3

Exam Tip

Take the perfect square outside and keep the remaining part inside. चरण 1: \(90=9 \times 10\) लिखें। चरण 2: \(\sqrt{90}=\sqrt{9 \times 10}=3\sqrt{10}\)। चरण 3: पूर्ण वर्ग को बाहर निकालकर शेष भाग अंदर रखें।

\(\sqrt{200}\) का सरल रूप कौन-सा है?

Which is the simplified form of \(\sqrt{200}\)?

Explanation opens after your attempt
Correct Answer

A. \(10\sqrt{2}\)

Step 1

Concept

\(200=100 \times 2\).

Step 2

Why this answer is correct

\(\sqrt{200}=\sqrt{100 \times 2}=10\sqrt{2}\).

Step 3

Exam Tip

Recognising a large perfect square like (100) gives the answer quickly. चरण 1: \(200=100 \times 2\) है। चरण 2: \(\sqrt{200}=\sqrt{100 \times 2}=10\sqrt{2}\)। चरण 3: बड़े पूर्ण वर्ग (100) को पहचानने से उत्तर जल्दी मिलता है।

\(\sqrt{8}+\sqrt{18}\) का सरल रूप क्या होगा?

What is the simplified form of \(\sqrt{8}+\sqrt{18}\)?

Explanation opens after your attempt
Correct Answer

A. \(5\sqrt{2}\)

Step 1

Concept

\(\sqrt{8}=2\sqrt{2}\) and \(\sqrt{18}=3\sqrt{2}\).

Step 2

Why this answer is correct

\(2\sqrt{2}+3\sqrt{2}=5\sqrt{2}\).

Step 3

Exam Tip

Radicals can be added only after they become like radicals. चरण 1: \(\sqrt{8}=2\sqrt{2}\) और \(\sqrt{18}=3\sqrt{2}\)। चरण 2: \(2\sqrt{2}+3\sqrt{2}=5\sqrt{2}\)। चरण 3: समान वर्गमूल बनने पर ही उन्हें जोड़ा जा सकता है।

What is the simplified form of \(\sqrt{125}\)?

Explanation opens after your attempt
Correct Answer

A. \(5\sqrt{5}\)

Step 1

Concept

Write \(125=25 \times 5\).

Step 2

Why this answer is correct

\(\sqrt{125}=\sqrt{25 \times 5}=5\sqrt{5}\).

Step 3

Exam Tip

Take the perfect square (25) outside as (5). चरण 1: \(125=25 \times 5\) लिखें। चरण 2: \(\sqrt{125}=\sqrt{25 \times 5}=5\sqrt{5}\)। चरण 3: पूर्ण वर्ग (25) को बाहर (5) के रूप में निकालें।
