Answer:

The answer to your question is 2i

Step-by-step explanation:

                                             \sqrt[4]{-16}

- Get the prime factors of -16

                                                  - 16   2

                                                   -  8  2

                                                   -  4  2

                                                   -  2  2

                                                       1

                                   16 = 2⁴

- Express the -16 as a power

                          \sqrt[4]{-2^{4}}  or   \sqrt[4]{2^{4}i^{2}}

Remember that -1 = i²

- Get the fourth root of -16

                                         2i

Lubov Fominskaja [6]

Answer: 1.4n represents the cost of n packages of pels.

1.20m represents cost of m pads.

Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.

Meaning of 1.4n  =  cost of n packages of pels.

Meaning of 1.20 m = represents cost of m pads.

where , 1.4 = Cost per package of pels

1.2 =Cost per pad of paper

Step-by-step explanation:

Given: Cost per package of pels = $1.40

Cost per pad of paper = $1.20

Number of packages of pels bought = n

Number of pads of paper bought = m

So, 1.4n represents the cost of n packages of pels.

1.20m represents cost of m pads.

Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.

Meaning of 1.4n  =  cost of n packages of pels.

Meaning of 1.20 m = represents cost of m pads.

where , 1.4 = Cost per package of pels

1.2 =Cost per pad of paper
