(Need Quick Help!) Which of the following expressions is equivalent to the one shown below ?
(-5 • 4)^3

A. (-5)^3•4^3

B. -15^3•12

C. -15•12

D. -8•7

Its A

Step-by-step explanation:

You must distribute exponents outside of parentheses to each

A = -5^3 × 4^3

B = multiplies each by 3 then raises 1 to the third, very off

C = just multiplied each by 3

D = very off, added by 3

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
