7. Examples - Complete Problem Answer 52*5 c3*c5 -3x2*4x5 48 ____ = 42 n9
25*35*52
__________ =
22*34*5

8. Examples - Complete Problem Answer 52*5 52+1 = 53 c3*c5 c3+5 = c8
52+1 = 53
c3*c5
c3+5 = c8
-3x2*4x5
(-3*4)(x2*x5) = -12(x2+5) = -12x7 48
____ = 42
48-2 = 46 n9 n4
n9-4 = n5
25*35*52
__________ =
22*34*5
(25-2)*(35-4)*(52-1) = 23*31*51 = 8*3*5 = 120
