For the first one: ...√2*11, + 1. Use PEMDAS, then find the square root of the answer.
→ √2*11, + 1
→ 2 times 11 = 22, plus 1 = 23.
→ √23 = 4.79583152331.
→ Then round to the nearest 10th = 4.79↑ = 4.8
For the second one: ... √4*8, + 1 + √2*8. Use PEMDAS, then find the square root to the answer.
→ √4*8, + 1 + √2*8
→ √32 + 1 + √16
→ √33 + √16
→ 5.74456264654 + 4
→ 9.74456264654
→ If you need to round to the tenth, 9.74↓ = 9.7
