we are given

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }$

we can use exponent formula

$a^n \cdot a^m=a^{n+m}$

now, we can use this formula

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{1}{2}+\frac{1}{2} }$

we can add exponent

and we get

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{1+1}{2} }$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{2}{2} }$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{1}$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2$

So, option-B.......Answer

You have a jar containing 55 coins, consisting entirely of nickels and quarters, worth a

yawa3891 [41]

Answer: 22 quarters

Step-by-step explanation:

Let N be the number of nickels.

Then the number of quarters is (55-N)

The nickels contribute 5N cents to the total.

The quarters contribute 25*(55-N) cents to the total.

5N + 25*(55-N) = 715

5N + 1375 - 25N = 715

-20N = 715 - 1375 = -660

$N=\frac{-660}{-20}$

$=33$

$55-33=22$

So there is 22 quarters inside the jar.

Check to see if my answer is correct-

33*5 + 22*25 = 715 cents
