Root 3 + root 2 /root 3- root 2 = a+b root 6

5 + 2

Step-by-step explanation:

Given

Multiply numerator/ denominator by the conjugate of the denominator

The conjugate of - is +

= ← expand numerator/ denominator using FOIL

=

=

= 5 + 2 → with a = 5 and b = 2

x=30

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
