Which expressions are equivalent to the one below? check all that apply. 3^4 • 3^x a. 34 - x b. 81 • 3x c. (3 • x)4 d. 34x e. 34 + x f. 94x

3^4+x, 81•3^x

Step-by-step explanation:

b, e

Step-by-step explanation:

just took the quiz

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
