Which expression is equivalent to the given expression?<br> (3m-4) (375)
Brilliant_brown [7]

9514 1404 393

Answer:

  D.  81/m^7

Step-by-step explanation:

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

Using these, your expression simplifies to ...

  (3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}

ch4aika [34]

ANSWER

2 \times 2

EXPLANATION

The dimensions of a matrix is of the form:

Row \times  Column

The dimensions of the first matrix is

2 \times 3

The dimensions of the second matrix is

3 \times 2

Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.

(2 \times 3)(3 \times 2) = 2 \times 2

Therefore the dimensions of the product is a 2×2 matrix.
