Question

slove with correct explanation ​

Answer 1

Answer:

root 45=6.708 and root 4.5=2.121

then root 4500=67.08 and root of 450 = 21.21

now adding them we get 88.29

Answer 2

Answer:

Option -C

Step-by-step explanation:

Given :-

√45 = 6.708

√4.5 = 2.121

To find :-

Find the value of √4500 + √450 ?

Solution:-

Given that

√45 = 6.708

√4.5 = 2.121

Now,

√4500 + √450

=> √(45×100) + √[(450)×(10/10)]

(On multiplying and dividing√450 with 10)

=> √(45×100) +√(4500/10)

=>√(45×100)+√[(45/10)×100]

=> √(45×100)+√(4.5×100)

=> 10×√45 + 10×√4.5

=> 10×(√45 + √4.5)

=> 10× (6.708+2.121)

=> 10× (8.829)

=> 88.29

Therefore, √4500 + √450 = 88.29

Answer:-

The value of √4500 + √450 for the given problem is 88.29

Used formulae:-

• √45 = 6.708
• √4.5 = 2.121
• √100 = √(10²) = 10
