Alisiya [41]

The product of the given two fractions are rational.

The given fractions include;

2/2 and 4/18

The product of the given fractions is calculated as follows;

\frac{2}{2} \times \frac{4}{18} = \frac{2}{9}

A rational number is a number that can be expressed in ratio form. These  numbers are two integers expressed in form of fractions called numerator and denominators.

Irrational numbers cannot be expressed in form of simple ratios.

Thus, we can conclude that the product of the given two fractions are rational.

riadik2000 [5.3K]
If \mathbf A is invertible, then we can simply choose \mathbf B=\mathbf A^{-1} because for any invertible matrix \mathbf X by definition we must have \mathbf{XX}^{-1}=\mathbf X^{-1}\mathbf X=\mathbf I.

We have \det\mathbf A\neq0, as

\det\mathbf A=\begin{vmatrix}1&7\\0&1\end{vmatrix}=1\times1-0\times7=1

which means \mathbf A is non-singular and has an inverse. The inverse itself would be

\mathbf A^{-1}=\dfrac1{\det\mathbf A}\begin{bmatrix}1&0\\-7&1\end{bmatrix}^\top=\begin{bmatrix}1&-7\\0&1\end{bmatrix}
