To find:
if given term is written as following:
<u>Solution:</u>
We can see that the resulting expression does not contain anything under (square root) so we need to rationalize the denominator to remove the square root from denominator.
The rule to rationalize is:
Any term having square root term in the denominator, multiply and divide with the expression by changing the sign of square root term of the denominator.
Applying this rule to rationalize the given expression:
Comparing the above expression with:
A = 5, B = 6 (Not divisible by square of any prime)
C = -10
D = 2 (positive)
GCD of A, C and D is 1.
So,
Answer:
There are 6 coins in nickels and 9 coins in quarters.
Step-by-step explanation:
Now, to find the solution.
According to question:
The number of nickels = .
The number of quarters =
So, the total number of coins:
He had 3 more quarters than nickels.
Thus,
.....(1)
Now, to get the solution:
Substituting the equation (1):
<em>Subtracting both sides by 3 we get:</em>
<em /><em />
<em>Dividing both sides by 2 we get:</em>
<em>The number of nickels = 6.</em>
Now, substituting the value of in equation (1):
<em>The number of quarters = 9.</em>
Thus, there are 6 coins in nickels and 9 coins in quarters.
