900,710,003 in expanded form

900,000,000+700,000+10,000+3

9.00710003  ×  10^8 or   900710003

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

9.00710003  ×  10^8

or

Write  900710003  as an equation.

answer:

1/9

step-by-step explanation:

to answer this, we "complete the square."

start with x^2+x.

1. identify the coefficient of the x term; it is 1.

2. halve this result, obtaining 1/2, and then square the latter:   (1/2)² = 1/4

3.   add 1/4 to, and then subtract 1/4 from, the original x^2+x:

      x^2+x + 1/4 - 1/4 this is exactly equivalent to   x^2+x.

4.   strictly speaking, the answer to this problem is 1/4, since adding 1/4 to  

x^2+x makes x^2+x into a perfect square.
