How did he get from 3^-16/3/3^-8/3 to 0.00285333857/0.00285333857??? (The circled part) Because when I put it in the calculator
I don’t get the decimal I was suppose to get.

We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=
. Hence CM=GC+GM=3*
. Now, since GM is normal to AB, we have by the pythagoeran theorem that:
Hence, we calculate from this that AC^2= 28, hence AC=2*
=BC. Thus, the perimeter of the triangle is 2+4*.
Hence, we calculate from this that AC^2= 28, hence AC=2*
Answer:
Step-by-step explanation:
1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:
·
·
2) The variables are fine - you can't simplify them further. All you need to do now is multiply the out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"
