You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer

Answer:
La base salarial de cada trabajador es de $ 425
Step-by-step explanation:
Aquí queremos calcular la base salarial de cada trabajador
Antes del incremento, sea la base salarial $ x
Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x
Con el incremento, cada uno ganará 3 (x + 50)
Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425
x + 50 = 1425/3
x + 50 = 475
x = 475 - 50
x = 425
Divide each term in
3x=27 by 3.3x3=27/3
Reduce the expression by cancelling the common factors.
Cancel the common factor.
3x3=27/3
Divide
x by 1.x =27 /3
Divide
27 by 3.x=9
Divide each term by 3 and simplify. hope this helps :)
