(8x^4+5x^3-6)-(2x^2-2x+6)

I got 8x^4+5x-2x^2+2x-12

convert the number to scientific notation.

19,450,000,000

I got 1.945x10^10

**gr**, Tuesday, December 16, 2008 at 11:37amyour first answer is right except the second term which should be 5x^3.

And writing in scientific notation, when moving decimal to left, exponent is negative, so correct answer will be 1.945*10^-10
