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
It is an expression that can be simplified to: 6x+1
It is an expression that can be simplified to: 3p+q
The expression can be simplified to: 12x-9
It is 16y+23x simplified
The given expression when simplified is: 5 -2q
76
-1?
It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
4√3 + 7√3 = (4 + 7)(√3) = 11√3
5/(8 + √7) = (40 - 5√7)/57 is the rationalised equivalent.
4 radical 6
The expression cannot be simplified.
What do you mean "simplified"? It can definitely be factored.
If that is l and not 1 then it is 3.5l+2s when simplified
The given expression cannot be simplified.
The expression is: 6-5x when simplified
There is no equation, only an expression. An expression can be simplified but cannot be solved.
