Answer 1

Answer:

$28 {m}^{7} {n}^{5}$

Step-by-step explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

${x}^{4} \times {x}^{2} = {x}^{6}$

Because

${x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6}$

Answer 2

Answer:

28m⁷n⁵

Step-by-step explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

m² + m⁵=m⁷

n⁵ + 0 = n⁵
