\(\sqrt{242}=11\sqrt{2}\), \(\sqrt{98}=7\sqrt{2}\), and \(\sqrt{32}=4\sqrt{2}\).
Step 2
Why this answer is correct
\(11\sqrt{2}+7\sqrt{2}-4\sqrt{2}=14\sqrt{2}\).
Step 3
Exam Tip
Convert all radicals into like form before adding or subtracting. चरण 1: \(\sqrt{242}=11\sqrt{2}\), \(\sqrt{98}=7\sqrt{2}\), और \(\sqrt{32}=4\sqrt{2}\)। चरण 2: \(11\sqrt{2}+7\sqrt{2}-4\sqrt{2}=14\sqrt{2}\)। चरण 3: सभी वर्गमूलों को समान रूप में बदलकर ही जोड़-घटाव करें।
\(\sqrt{245}=7\sqrt{5}\), \(\sqrt{180}=6\sqrt{5}\), and \(\sqrt{80}=4\sqrt{5}\).
Step 2
Why this answer is correct
\(7\sqrt{5}+6\sqrt{5}-4\sqrt{5}=9\sqrt{5}\).
Step 3
Exam Tip
Before addition or subtraction, write all radicals in like form. चरण 1: \(\sqrt{245}=7\sqrt{5}\), \(\sqrt{180}=6\sqrt{5}\), और \(\sqrt{80}=4\sqrt{5}\)। चरण 2: \(7\sqrt{5}+6\sqrt{5}-4\sqrt{5}=9\sqrt{5}\)। चरण 3: जोड़-घटाव से पहले सभी वर्गमूलों को समान रूप में लिखें।
\(\sqrt{128}=8\sqrt{2}\), \(\sqrt{72}=6\sqrt{2}\), and \(\sqrt{50}=5\sqrt{2}\).
Step 2
Why this answer is correct
\(8\sqrt{2}+6\sqrt{2}-5\sqrt{2}=9\sqrt{2}\).
Step 3
Exam Tip
Convert all radicals into like form before adding or subtracting. चरण 1: \(\sqrt{128}=8\sqrt{2}\), \(\sqrt{72}=6\sqrt{2}\), और \(\sqrt{50}=5\sqrt{2}\)। चरण 2: \(8\sqrt{2}+6\sqrt{2}-5\sqrt{2}=9\sqrt{2}\)। चरण 3: सभी वर्गमूलों को समान रूप में बदलकर ही जोड़-घटाव करें।
\(\sqrt{75}=5\sqrt{3}\), \(\sqrt{300}=10\sqrt{3}\), and \(\sqrt{48}=4\sqrt{3}\).
Step 2
Why this answer is correct
\(5\sqrt{3}+10\sqrt{3}-4\sqrt{3}=11\sqrt{3}\).
Step 3
Exam Tip
Simplify all radicals before addition and subtraction. चरण 1: \(\sqrt{75}=5\sqrt{3}\), \(\sqrt{300}=10\sqrt{3}\), और \(\sqrt{48}=4\sqrt{3}\)। चरण 2: \(5\sqrt{3}+10\sqrt{3}-4\sqrt{3}=11\sqrt{3}\)। चरण 3: जोड़ और घटाव से पहले सभी वर्गमूलों को सरल करें।
\(\sqrt{98}=7\sqrt{2}\), \(\sqrt{50}=5\sqrt{2}\), and \(\sqrt{18}=3\sqrt{2}\).
Step 2
Why this answer is correct
\(7\sqrt{2}+5\sqrt{2}-3\sqrt{2}=9\sqrt{2}\).
Step 3
Exam Tip
Add or subtract only after converting all terms to like radicals. चरण 1: \(\sqrt{98}=7\sqrt{2}\), \(\sqrt{50}=5\sqrt{2}\), और \(\sqrt{18}=3\sqrt{2}\)। चरण 2: \(7\sqrt{2}+5\sqrt{2}-3\sqrt{2}=9\sqrt{2}\)। चरण 3: सभी पदों को समान वर्गमूल में बदलने के बाद ही जोड़-घटाव करें।
\(\sqrt{45}=3\sqrt{5}\), \(\sqrt{80}=4\sqrt{5}\), and \(\sqrt{20}=2\sqrt{5}\).
Step 2
Why this answer is correct
\(3\sqrt{5}+4\sqrt{5}-2\sqrt{5}=5\sqrt{5}\).
Step 3
Exam Tip
Convert all radicals to like form before adding or subtracting. चरण 1: \(\sqrt{45}=3\sqrt{5}\), \(\sqrt{80}=4\sqrt{5}\), और \(\sqrt{20}=2\sqrt{5}\)। चरण 2: \(3\sqrt{5}+4\sqrt{5}-2\sqrt{5}=5\sqrt{5}\)। चरण 3: जोड़ और घटाव से पहले सभी वर्गमूलों को समान रूप में बदलें।
