- ✓$3b^2c^2$
- C$15b^2c^4$
- D$12b^2c^4$
✓
Answer
Correct option: B.
$3b^2c^2$
B. $3b^2c^2$
Solution:
$3a^2b^4c^2 = 3 \times a \times a \times b \times b \times b \times b \times c \times c$
$12b^2c^4 = 2 \times 2 \times 3 \times b \times b \times c \times c \times c \times c$
$15a^3b^4c^4 = 3 \times 5 \times a \times a \times a \times b \times b \times b \times b \times c \times c \times c \times c$
Solution:
$3a^2b^4c^2 = 3 \times a \times a \times b \times b \times b \times b \times c \times c$
$12b^2c^4 = 2 \times 2 \times 3 \times b \times b \times c \times c \times c \times c$
$15a^3b^4c^4 = 3 \times 5 \times a \times a \times a \times b \times b \times b \times b \times c \times c \times c \times c$
