When multiplying powers, you add them! y4 times y6 = y10. Try it with y = 2: 2 to the fourth = 16, 2 to the sixth = 64 16 x 64 = 1024 = 2 to the tenth.
The product is (xy - 3x + 4y -12).I got that by performing the multiplication of (x + 4) (y - 3) .
(4y)-2
You multiply the unit cost by the number of units. The product of y and 4 is 4y.
x + y = 5xy=41 and 4 works. ■
abs(y^3 - 4) < 8*y

39 * 406 = 15834
xy = 20 x+y=9 x=9-y y(9-y) = 20 9y-y(squared) = 20 0= y(squared)-9y+20 0= (y-5)(y-4) y= 5 or 4, x= 5 or 4 The two numbers are 5 and 4.
-2
x + y = 5xy=41 and 4 works. ■
x=2 and y=3
xy=-60 x+y=11 x=11-y (11-y)y=-60 x=11+4= 15 or x=11-15= -4 11y-y2+60=0 y= -4 or 15 so the answer is 15 and -4 or -4 and 15
