Simplify. (3x5+3x2−4x3+x−6)−(x3+4x4+2x2−10x) Enter your answer, in standard form, in the box.

Snezhnost [94]

All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.

This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x

Then combine like terms and line all the values in order from greatest exponent value to least to get
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6

Hope this helped :)

What is 0.0003840 expressed in scientific notation

neonofarm [45]

You can write the fraction 0.0003840 a number of ways.
0.0003840 = 0.003840/10 = 0.03840/100 = 0.3840/1000 = 3.840/10000

The one we're interested in is the last one, which has one non-zero digit to the left of the decimal point. The power of 10 in the denominator is the 4th power (the number of zeros is 4). 10^4 in the denominator is equivalent to multiplying by 10^(-4) in the numerator.

Expressed in scientific notation,
$0.0003840=3.840 \cdot 10^{-4}$
