Simplify square root of 5 open parentheses 10 minus 4 square root of 2 close parentheses.
Solution:
It is given that square root of 5 open parentheses 10 minus 4 square root of 2 close parentheses
We can write it as √5(10 - 4√2)
Using the multiplicative distributive property
√5(10 - 4√2) = 10√5 - 4√2√5 = 10√5 - 4√10
Therefore, by simplifying we get (10√5 - 4√10).
Example -
Simplify square root of 2 open parentheses 5 minus 3 square root of 2 close parentheses.
Solution:
It is given that square root of 2 open parentheses 5 minus 3 square root of 2 close parentheses
We can write it as √2(5 - 3√2)
Using the multiplicative distributive property
√2(5 - 3√2) = 5√2 - 3√2√2 = 5√2 - 3 × 2 = 5√2 - 6
Therefore, by simplifying we get (5√2 - 6).
Simplify square root of 5 open parentheses 10 minus 4 square root of 2 close parentheses.
Summary:
Simplifying square root of 5 open parentheses 10 minus 4 square root of 2 close parentheses we get (10√5 - 4√10).
