<span>(12xy)^2
Expand:
12^2*x^2*y^2
= 144x^2*y^2</span>
You take 16 and -5 and subtract them to get the answer which is 11
Y = (-2)3 - 3
Y = -6 - 3
Y= -9
-x/y is equivalent to x/-y according to the division rule a/b*d/c=a/b*c/d.
<h3>Describe division.</h3>
In division, a number is divided, which is an easy operation. In mathematics, division is the division of a sum into equal parts. A group of 20 people, for instance, could be divided into four groups of 5, five groups of 4, and so on. Division's opposite is multiplication. If 3 groups of 4 add up to 12, then 4 are in each group when 12 is divided into 3 equal groups.
According to the division rule a/b/c/d=a/b*d/c,
=1/(y/-x)
=1*-x/y
=-x/y
-x/y is equivalent to x/-y according to the division rule a/b÷c/d=a/b*d/c.
