We have been given an expression $(8.5\times 10^3)(2\times 10^5)$ . We are asked to find the solution to our given expression expressed as scientific notation.

Let us simplify our given expression.

Using exponent property $a^m\cdot a^n=a^{m+n}$ , we will get:

$8.5\times 2\times 10^3\times 10^5$

$17\times 10^{3+5}$

$17\times 10^{8}$

Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:

$1.7\times 10\times 10^{8}$

$1.7\times 10^{1+8}$

$1.7\times 10^{9}$

Therefore, our required solution would be $1.7\times 10^{9}$ .

Write the opposite polynomial for -3x ^3+12x-4

ValentinkaMS [17]

Answer:

3x³ - 12x + 4

Step-by-step explanation:

The opposite of a polynomial P is -P.

You find the opposite of P by multiplying it by -1.

P = -3x³ + 12x - 4

-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term

= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1

= 3x³ + (-12)x - (-4)

= 3x³ - 12x + 4
