Answer:

commutative property: the property stating that changing the order in which two numbers are added or multiplied does not change the value of the sum or product

equivalent: having the same amount, value, area, volume, or force

evaluate: to determine the value of

like terms: terms consisting of the same variables, raised to the same exponent

Answer:

Sample Response: Model the second expression using 6 positive x tiles, 4 negative tiles, and then one negative x tile. The negative x tile forms a zero pair with one of the positive x tiles, leaving 5 positive x tiles and 4 negative tiles. This is not equivalent to 7x – 4.

Help! <br> Which expression is equivalent? <br> On edge

Ira Lisetskai [31]

Answer: Choice B

$x^{1/8}y^{8}$

======================================================

Explanation:

The two rules we use are

$(a*b)^c = a^c*b^c$

$(a^b)^c = a^{b*c}$

When applying the first rule to the expression your teacher gave you, we can say that:

$\left(x^{1/4}y^{16}\right)^{1/2} = \left(x^{1/4}\right)^{1/2}*\left(y^{16}\right)^{1/2}$

Then applying the second rule lets us say

$\left(x^{1/4}\right)^{1/2}*\left(y^{16}\right)^{1/2} = x^{1/4*1/2}*y^{16*1/2} = x^{1/8}y^{8}$

Therefore,

$\left(x^{1/4}y^{16}\right)^{1/2} = x^{1/8}y^{8}$

-------------

In short, we just multiplied each exponent inside by the outer exponent 1/2.

So that explains why the exponents go from {1/4,16} to {1/8,8} for x and y in that exact order.
