Answer:

Commutative

Step-by-step explanation:

Given

3 + b + 2 = 3 + 2 + b

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

a + b = b + a

So:

3 + b + 2 = 3 + (b + 2)

When the positions of 2 and b are interchanged, we have:

3 + b + 2 = 3 + (2 + b)

Remove bracket

3 + b + 2 = 3 + 2 + b

What is the value of b in the equation (y^-9)^b=y^45?
nevsk [136]

Answer:

b = (log(y^45))/log(1/y^9) + (2 i π n)/log(1/y^9) for n element Z

Step-by-step explanation:

OLga [1]
Well if 49 is the area, and you get area by multiplying one side by another side, and its a square so the numbers are going to be the same, so you would be multiplying two of the same numbers. And two of the same numbers that equal 49 is 7.
