Answer:
Calculate the determinant. Calculate the matrix of cofactors. Transpose the matrix of cofactors to obtain the adjugate matrix. Divide each entry of the adjugate matrix by the determinant to obtain the inverse.
Answer: 9/10
Step-by-step explanation:
To get the answer, 3/5 ÷ 2/3
= 3/5 × 3/2
=multiply the numerators: 3 x 3 = 9
Multiply the denominators: 5 x 2= 10
Therefore, the answer is 9/10.
Answer:
The correct answer is last option
2n + m√n - nm
Step-by-step explanation:
It is given an expression,
4√n² + √m²n - √4n² - √mn²
<u>To simplify the expression</u>
4√n² + √m²n - √4n² - √mn² = 4n + m√n -2n -nm
= 4n - 2n + m√n - n√m
= 2n + m√n - n√m
Therefore the correct answer is last option
