Answer:
3x^4 + 7x^3 - 5x^2 + 8x - 13
Step-by-step explanation:
(3x^4 + 7x^3 - 9) - (5x^2 - 8x + 4) =
The negative sign to the left of the second set of parentheses changes every sign inside the parentheses.
The first set of parentheses is unnecessary, so we just drop it.
= 3x^4 + 7x^3 - 9 - 5x^2 + 8x - 4
Now we combine like terms.
= 3x^4 + 7x^3 - 5x^2 + 8x - 13
If we use the rules we say that <span>when we multiply two numbers we get the result in the numbers the least significant number has in the multiplication. So we may proceed like this:</span>
67.6 x 1.2 = 81.12
<span>As the decimal part does not continue indefinitely we can leave the answer as it is.</span><span> if the answer was 81.123612356213 then we leave it like </span><span>81.1 as the rules say</span>
