Write a polynomial expression that has the following characteristics: The polynomial expression is a binomial.
The polynomial expression has degree 4.
The leading coefficient is 7.

7x^4+x^3 (or 7x^4 + some random term)

Step-by-step explanation:

Since the polynomial expression must be a binomial, it must have two terms.

Since the binomial must have a degree of 4, and the leading coefficient must be 7, then a possible binomail could be 7x^4+x^3 because you have two terms, 7x^4 and x^3 while the degree is 4 and the leading coefficient is 7.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
