What is 6.16×10^6 in standard form?

a.6,160,000

b.61,600,000

c.601,600,000

d.616,000,000

A.  6,160,000

Step-by-step explanation:

Given number = 6.16×10^6

This can be represented as 6.16 * 1000000

In order to multiply the two numbers , we need to move the decimal point 6 places to the right and add zeros as fillers for missing digits.

Step1 : 61.6 * 10^5

Step2: 616 * 10^4

Step3: 6160 * 10^3

Step4: 61600 * 10^2

Step5: 616000 * 10^1

Step6: 6,160,000

So the standard form representation of the given number is 6,160,000.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
