What is 400,000 times 200 in scientific notation

2 answers:

8 0

If you move the decimal point left until it is just to the right of the most-significant digit, the number of places you moved it is the power of ten that your new number is multiplied by.

$400,000=4\times 10^{5}\\200=2\times 10^{2}$

Then multiplication can proceed in the usual way, taking into account the rules of exponents.

$4\cdot 10^{5}\times 2\cdot 10^{2}=8\cdot 10^{(5+2)}\\\\=8\cdot 10^{7}$

F(x) = 5x^2 + 9x – 4<br> g(x) = – 8x^2 – 3x – 4<br> Find (f + g)(x).

svp [43]

Answer:

(f + g)(x) = – 3x^2 + 5x - 8

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

= 5x^2 + 9x – 4 + (– 8x^2 – 3x – 4)

= 5x^2 + 9x – 4 – 8x^2 – 3x – 4

Combine

= – 3x^2 + 5x - 8
