Answer:
2.389 x 10^5
Step-by-step explanation:
First, write both numbers out. Move the decimal point right however many times the exponent says. For 8.9, we move the decimal right 3 times, and we would move it right 5 times for 2.3.
230000
<u>+ 8900</u>
238900
Now let's convert this to scientific form. The beginning number in scientific form has to be between 1 and 10, so move the decimal point left until you get a number that fits. Here, we will move it 5 times.
2.38900
Because we've moved it left 5 times, we make the exponent 5.

Answer:
B
Step-by-step explanation:
the product (2x² - 3x - 8)(3x² + 5x + 1) is required
multiply each term in the second factor by each term in the first factor.
= 2x²(3x² + 5x + 1) - 3x(3x² + 5x + 1) - 8(3x² + 5x + 1) ← distribute
= 6 + 10x³ + 2x² - 9x³ - 15x² - 3x - 24x² - 40x - 8
collecting like terms gives
6 + x³ - 37x² - 43x - 8 → B
