When written in scientific notation, the number 4,500 will have a Choose...
as the exponent on the power of ten.

The number 4,500 is written in scientific notation as 4.5 x 103. The coefficient is 4.5. The coefficient must be a number greater than or equal to 1 and smaller than 10. The power of 10 or exponent in this example is 3.

Step-by-step explanation:

I believe the answer is 3. Sorry if incorrect.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i would need to see the dot plot : )
