Order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.
<h3>What is a matrix?</h3>- A matrix is a rectangular array or table of numbers, symbols, or expressions that are organized in rows and columns to represent a mathematical object or an attribute of such an object in mathematics.
- For instance, consider a matrix with two rows and three columns.
To find the order of matrix:
- We must first check the dimension of two matrices, say matrix A by matrix B, before we may multiply them.
- Multiplication is achievable if the number of columns in the first matrix, A, equals the number of rows in the second matrix.
- Dimension is assigned to the provided matrix: 6 × 5
- This means the given matrix contains six rows and five columns.
- As a result, the second matrix MUST have 5 rows in order for multiplication to be POSSIBLE.
- The only matrix with 5 rows among the above alternatives is the matrix with dimension (B) 5 × 6.
To prove:
- In other words, the inner products of the dimensions should be equal.
- That is; (a × b)(b × a) is possible but (a ×b)(c × b) is impossible.
- The dimensions of the matrix are given by, row × column.
Therefore, order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.

Answer:
A. 4 (RootIndex 3 StartRoot 7 x EndRoot) or
Step-by-step explanation:
Given:
A radical whose value is,
Now, we need to find the like radical for .
Let the like radical be .
As per the definition of like radicals, like radicals are those that can be expressed as multiples of each other.
So, if two radicals are like radicals, then
Where, 'n' is a real number.
Here,
Now, let us check all the options .
Option A:
4 (RootIndex 3 StartRoot 7 x EndRoot) or
Now, we observe that is a multiple of
because
Therefore, option A is correct.
Option B:
StartRoot 7 x EndRoot or
As the above radical is square root and not a cubic root, this option is incorrect.
Option C:
x (RootIndex 3 StartRoot 7 EndRoot) or
As the term inside the cubic root is not same as that of , this option is also incorrect.
Option D:
7 StartRoot x EndRoot or
As the above radical is square root and not a cubic root, this option is incorrect.
Therefore, the like radical is option (A) only.
