(3.8 x 10 ^ -6) x (2.37 x 10 ^ -3)<br><br> Enter the answer in science notification

Black_prince [1.1K]

Multiply the coefficients and the powers of 10 with each other:

$(3.8 \times 10^{-6}) \times (2.37 \times 10^{-3}) = (3.8\times2.37) \times (10^{-6} \times10^{-3})$

The numeric part simply yields

$3.8\times2.37 = 9.006$

As for the powers of 10, you have to add the exponents, using the rule

$a^b \times a^c = a^{b+c}$

So, we have

$10^{-6} \times10^{-3} = 10^{-6-3} = 10^{-9}$

So, the final answer is

$9.006\times 10^{-9}$

Joni made a down payment of $1,600 on a car that was 20% of the total price what was the total price

zvonat [6]

We know that 20 percent is 1/5
$1,600 = (1/5)*x\\ 1,600 * 5 = x 8,000 = x$
total price is $8,000

What is the correct answer

tiny-mole [99]

Take a look at all 3 expressions: numbers, terms, and exponents.

4, 8, and 6 all have a GCF of 2.

y^5, y^3, and y^2 have a GCF of y^2.

Therefore, the GCF is 2y^2. Removing it gets you:

2y^2(2y^3 + 4y - 3)
