The correct answer is 4x^3y^2(\sqrt[3]{4xy}).

When we list the prime factorization of 256x^10y^7, we want to look for triples (this is a cubed root):

256 = 2³(2³)(2²)
x^10 = x³(x³)(x³)x
y^7 = y³(y³)y

Taking out our triples, we have 
2*2*x*x*x*y*y outside the cubed root, with 2²(x)(y) left inside:
2(2)(x)(x)(x)(y)(y)\sqrt[3]{2^2xy}
\\
\\=4x^3y^2\sqrt[3]{4xy}

IrinaK [193]
ANSWER:
15 SLICES

Explanation:
Joe ate 2 slices (1/4 = 2/8), Rhoda ate 3 (3/8), Chris ate 4.
2+3+4= 9.
There are 3 pizzas divided into 8 slices per pizza.
3 x 8 = 24 ; 24 SLICES TOTAL
Subtract 9 (that’s what was consumed) from 24.
24-9 = 15 ; 15 SLICES LEFT OVER

Use one or more properties to rewrite the expression as an equivalent expression that does not use parenthesis. (5+10p)+13. A. 2
bulgar [2K]
It will be D. because you have to add the like terms which is 13 + 5 which will be 18 and so 10p doesn't have no like terms it just stays the same so it will be 10p+18

Cassandra cuts 5/8 inch off the top of a photo and 3/8 inch off the bottom. How much shorter is the total height of the photo no
Daniel [21]
Just add together these two fractions to determine by how much the height of the photo is shortened.  5/8 plus 3/8 comes to 8/8, or 1.

The photo is now 1 inch shorter than it was originally.
