Look at the prime factorization. If all the factors have powers that are multiples of 6, then the number is a square and a cube. If they are multiples of 3, then a cube; if multiples of 2, then a square.
1000 = 2³·5³ . . . . a perfect cube
4 = 2² . . . . a perfect square
120 = 2³·3·5 . . . . none of the above (not a square or a cube)
36 = 2²·3² . . . . a perfect square
100 = 2²·5² . . . . a perfect square
49 = 7² . . . . a perfect square
125 = 5³ . . . . a perfect cube
25 = 5² . . . . a perfect square
Answer:
C
Step-by-step explanation:
the conference interval
Answer:1/3
Step-by-step explanation:
Answer:
w = (0, 15)
Step-by-step explanation:
w²-15w =0
w(w-15)=0
w=0 , w=15
if w=0
0(0-15)=0
0(-15)=0
0=0
if w=15
15(15-15)=0
15(0)=0
0=0
