Use scientific notation to find 508,000,000,000 x 0.0000073. Write the answer in scientific and in standard form.
defon

Answer:

3.7084 x 10^6   (scientific form)

3,708,400 (standard form)

Step-by-step explanation:

Expressing these numbers in scientific notation:

508,000,000,000 = 5.08 x 10^11

0.0000073 = 7.3 x 10^-6

Hence,

508,000,000,00 x 0.0000073

= (5.08 x 10^11)     x    (7.3 x 10^-6)

= 5.08 x 7.3 x 10^11 x 10^-6

= 37.084 x 10^ [11 + (-6)]

= 37.084 x 10^5

= 3.7084 x 10 x 10^5

= 3.7084 x 10^6   (scientific form)

= 3,708,400 (standard form)

Use properties of rational exponents to simplify the expression. Assume that all variables represent positive numbers. Superscri
blsea [12.9K]

Hi, your question was incomplete hence I have attached the complete version of the question below.

Answer:

<u>5x^3 y^2</u>

Step-by-step explanation:

Using the property of the product of the exponents on the base and removing the parentheses,

(125x^9y^6)^(1/3) = (125)^(1/3) * (x^9)^(1/3) * (y^6)^(1/3)

= (125)^(1/3) * (x)^9*(1/3) * (y)^6*(1/3)

= 5 * (x)^3 * (y)^2                                                    

= 5 x^3 y^2

hence the required result is 5 x^3 y^2

The sum of two positive integers, x and y, is not more than 40. The difference of the two integers is at least 20. Chaneece choo
oksian1 [2.3K]
<span>Chaneece chooses x as the larger number and uses the inequalities y ≤ 40 – x and y ≤ x – 20 to determine the possible solutions.

</span>y ≤ 40 – x, if x must be between 0 and 10, y must be between 20 and 40 <span>it is true
proof
</span><span>for x=0  and y=10,  y ≤ 40 – x equivalent to 10<40-0=40 it is true
</span>x=10, y=30,   <span>y ≤ 40 – x  equivalent to 30=40-10=30 it is true

the answer is </span><span>A) Yes, Chaneece found the correct solution. </span>
