Answer:=
y^(97)
Step-by-step explanation:
Given the expression
(y 3)2 *y 7* y17* y12 *y42 *y13
We can apply the law of indices for the multiplication of the given expression
The law one to be specific states that If the two terms have the same base (in this case y) and are to be multiplied together their indices are added.
Y^m*y^n= y^(m+n)
=(y 3)2 *y 7* y17* y12 *y42 *y13
=y 6 *y 7* y17* y12 *y42 *y13
=y^(6+7+17+12+42+13)
=y^(97)
B (:
cuz i saw it on this other website and i am like 50% sure its correct
For this case we must multiply the following expression:
By definition of properties of otencias and roots we have:
We rewrite the terms of the expression:
So, we have:
Applying the above definition we have:
We multiply the exponents:
We combine using the product rule for radicals.
By definition of multiplication properties of powers of the same base, we put the same base and add the exponents:

Using a system of equations, Brian should use 3 pounds of almonds and 9 pounds of hazelnut to make the mixture.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Number of pounds of almonds.
- Variable y: Number of pounds of hazelnut.
Considering that he makes 12 pounds, at a price of 12 x 10.35 = $124.2, the equations are given as follows:
From the first equation, y = 12 - x, hence, replacing in the second:
10.8x + 10.2y = 124.2
10.8x + 10.2(12 - x) = 124.2
0.6x = 1.8
x = 1.8/0.6
x = 3
y = 12 - x = 12 - 3 = 9.
Brian should use 3 pounds of almonds and 9 pounds of hazelnut to make the mixture.
