Prime factorizations are expressions of numbers as products of prime factors. The prime factorization of 30 is 2 x 3 x 5.
10 = 2 × 5
2 x 29 = 58
Rosa is 10. -- further-- This is calculated by working out the relationship between the children. Let's call Rosa "R" and let that stand for her age. The next child is R + 2 years old and the eldest if R + 4. We are told that R + (R + 2) + (R + 4) = 36 (add the Rs and the digits on the left) R + R + R + 2 + 4 = 36 3R + 6 = 36 (subtract 6 from both sides) 3R = 36 - 6 3R = 30 (divide both sides by 3) R = 10According to the information given, Rosa is ten years old.
A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6
There's only one. 2 x 2 x 13
30 = 2 × 3 × 5 36 = 2 × 2 × 3 × 3
Prime factorizations are expressions of numbers as products of prime factors. The prime factorization of 30 is 2 x 3 x 5.
30, 33 and 36 have 3 in their prime factorizations.
54 = 2*3*3*3 36 = 2*2*3*3
10 = 2 × 5
2 x 2 x 3 x 3 = 36 2 x 2 x 2 x 3 x 7 = 168
24 x 33 = 432
2 x 29 = 58
49 = 7 x 7 or 72
2 x 2 x 13 = 52
36 times with a 3 remainder
