Question

What is the approximate 47? Give your answer and explain why it is correct. HELP

Answer 1

Explanation:

`6^(2) =36\\7^2=49\\therefore,6< √(47) <7,\\6.5^2=42.25,\\therefore,6.5< √(47) <7,\\6.75^2=45.5625\\therefore,6.75< √(47) <7\\6.85^2=46.9225\\therefore,6.85< √(47) <7\\6.9^2=47.61\\therefore,6.85< √(47) <6.9`

Answer 2

7

Explanation:

7 is approximate to
`√(47)` because 7 is
`√(49)`, and 49 is close to 47
