5 radical 2 (5√2)

76

√5

just round off the number after the decimal if it is above 5.

Sqrt(20) = sqrt(5)*sqrt(4) = 2*sqrt(5)

5/(8 + âˆš7) = (40 - 5âˆš7)/57 is the rationalised equivalent.

13z-9

2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7

3 radical 5

It is an expression that can be simplified to: 3x-20

6âˆš5 + 2âˆš5 - 7 = 8âˆš5 - 7, which cannot be simplified.

sqrt(3) x sqrt(15) = sqrt( 3 x 15 ) = sqrt( 45 ) = sqrt( 9 x 5 ) = 3 sqrt(5)

Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.

The trick here is to multiply by the value 1, but express it as (5 - √5)/(5 - √5). This forms a difference of squares on the bottom, eliminating the radical:(1 + √5) / (5 + √5)= (1 + √5)(5 - √5) / (5 + √5)(5 - √5)= (5 - √5 + 5√5 - 5) / (25 - 5√5 + 5√5 - 5)= 4√5 / 20= √5 / 5

The expression cannot be simplified.

It can not be simplified any more. To the nearest hundredth, 6.71

33z - 4 - 20z - 5 simplified would be 13z - 1.

If you mean: 33z-4-20z-5 then it is 13z-9 when simplified
