Its kinda hard to explain but its the answer
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied
(2^6)=1
take log on both sides,
xlog(2^6)=log(1)=0
=>
x=0, since log(2^6)>0
5^0=1
there is no value of x appearing in the equation, so x can be any valid number.
The logarithm of a product is equal to the sum of logarithms:

Drop the exponents:

The logarithm of a number is equal to 1 if the base of the logarithm is the same as the number itself:

Answer:
The stock Norman purchased increased in its value by 25%.

New(Current) value of the stock = $ 525
We have to find the percentage change in the value of stock. The formula to calculate the percentage change is:

Substituting the given values into this formula results in:

A positive value of Percentage Change indicates a growth. This means that the stock Norman purchased increased in its value by 25%.
