Answer 1

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

Answer 2

sqrt(2x+1) when x=11

sqrt(2*11+1)

sqrt(22+1)

sqrt(23)

4.79583

to the nearest tenth

4.8

sqrt(4x+1) + sqrt(2x) when x=8

sqrt(4*8+1) + sqrt(2*8)

sqrt(32+1) + sqrt(16)

sqrt(33) + 4

5.7446 +4

9.7446

rounding to the nearest tenth

9.7
