Answer:

  • [tex]5+\sqrt{5}[/tex]

Step-by-step explanation:

Both are essentially same questions, considering 30 = 25 + 5.

Solving c)

  • [tex]\sqrt{25+10\sqrt{5} +5} =[/tex]
  • [tex]\sqrt{5^2+2*5*\sqrt{5} +(\sqrt{5} )^2} =[/tex]
  • [tex]\sqrt{(5+\sqrt{5} )^2} =[/tex]
  • [tex]5+\sqrt{5}[/tex]

Solution:

Part-C)

  • √25 + 10√5 + 5
  • => √25 + 10 × √5 + 5
  • => √25 + 10 × 2.236 + 5 [√5 = 2.236 according to the table uploaded]
  • => √25 + 22.36 + 5
  • => √52.36 = 7.236

Part-D)

  • √30 + 10√5
  • => √30 + 10 × √5
  • => √30 + 10 × 2.236 [√5 = 2.236 according to the table uploaded]
  • => √30 + 22.36
  • => √52.36 = 7.236

Hoped this helped!
