The expression $y^{n}$ represent the repeated multiplication of $y$ , $n-$ times. The repeated multiplication of the same factor is called power.

The variable y is called the base and n is called the exponent or index.

<h2>Hence the correct answer is C.</h2>

if there are two containers of sugar solution, the first is 4% concentration and second is 8% concentration. how much of each sh

Elina [12.6K]

Answer:

30 gallons solution 4% and 10 gallons solution 8%

Step-by-step explanation:

4x+8y=40•5 and x+y=40

x=40-y

4(40-y)+8y=200

160-4y+8y=200

4y=200-160

4y=40 => y=10 (gallons solution 8%)

=> x=40-10=30 (gallons solution 4%)

30 gallons solution 4% and 10 gallons solution 8%
