Crank

Note: Consider the expression is (4+\sqrt{2})(6-\sqrt{2}).

Given:

(4+\sqrt{2})(6-\sqrt{2})

To find:

The value of given expression in the form of b+c\sqrt{2}.

Solution:

We have,

(4+\sqrt{2})(6-\sqrt{2})

Using distributive property, we get

=4(6-\sqrt{2})+\sqrt{2}(6-\sqrt{2})

=4(6)+4(-\sqrt{2})+\sqrt{2}(6)+\sqrt{2}(-\sqrt{2})

=24-4\sqrt{2}+6\sqrt{2}-2

On combining like terms, we get

=(24-2)+(6\sqrt{2}-4\sqrt{2})

=22+2\sqrt{2}

On comparing with b+c\sqrt{2}, we get

a=22,b=2

Therefore, the required form is 22+2\sqrt{2}.

Verify a-(-b) =a + b for the following values of ‘a’ and ‘b’: (a) a = 34; b=73 (b) a = 45; b=30
Margaret [11]

Step-by-step explanation:

(a)

34 - (-73) = 34 + 73

34 + 73 = 107

107 = 107

(b)

45 - (-30) = 45 + 30

45 + 30 = 75

75 = 75
