Answer:
The value of
-
is 3 ⇒ 2nd
Step-by-step explanation:
The dimensions of any matrix are (m × n), where
- m is the number of its row
- n is the number of its column
Ex: Matrix A of dimensions (2 × 3) has 2 rows and 3 columns, where
means the element in the 1st row and 1st column
means the element in the 1st row and 2nd column
means the element in the 1st row and 3rd column
means the element in the 2nd row and 1st column
means the element in the 2nd row and 2nd column
means the element in the 2nd row and 3rd column
Now lets solve the problem
∵ The matrix B has 3 rows
∴ m = 3
∵ The matrix B has 4 columns
∴ n = 4
∴ The dimensions of matrix B are (3 × 4)
∵
means the element in the 2nd row and 4th column
∴
= 9
∵
means the element in the 3rd row and 2nd column
∴
= 6
- Find the value of
- 
∵
-
= 9 - 6
∴
-
= 3

Answer:
7p¹⁵/ 3q¹²
Step-by-step explanation:
From the question given above,
28p⁹q¯⁵ / 12p¯⁶q⁷
To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:
28p⁹q¯⁵ / 12p¯⁶q⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷
Recall:
Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ
Therefore,
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²
Recall:
X¯ⁿ = 1/Xⁿ
Therefore,
(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²
(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²
Hence,
28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²
