Answer 1

Sq root of 8 = sq root of 4× 2=2root2

Sq of 50= sq root of 2× 25= 5root2

Sq root 72= sq root of 2×36=6root2

Sq root of 98=sq root of 2×49=7root2

Adding = 20root 2= 20 × 1.414=28.28

Answer 2

The answer for the given question is 28.28.

Step-by-step explanation:

• Given: √2 = 1.414.
• To solve: √8 + √50 + √72 + √98.
• The first step is to find the factors of the given numbers.
• Step 1: √8 = √2*2*2 = 2√2.
• Step 2: √50 = √2*5*5 = 5√2.
• Step 3: √72 = √8*9 = √2*2*2*3*3 = 6√2.
• Step 4: √98 = √2*7*7 = 7√2.
• Adding all the steps, we get  2√2 + 5√2 + 6√2 + 7√2 = 20√2 = 20 * 1.414 =28.28.
• Hence, the answer is 28.28.
