The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 ×
- 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 ×
- 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 ×
is 7999800 times larger than 2 × 10².

Step-by-step explanation:
Answer:
-x^3*(x + 1)
Step-by-step explanation:
Perform the indicated multiplication and then write out all the terms in descending order by powers of x:
-x^3(5x+1)+4x^4 = -5x^4 - x^3 + 4x^4
= -x^4 - x^3, or = -x^3*(x + 1)
