Answer:

7. (7^2)(4^2) or 49 * 16

8.18^5

Step-by-step explanation:

7. You can do that or simplify the exponents.

8. When dividing two exponents you can subtract the exponentes. *(note i didn't simplify 18^5 because it said expression, and a simplified number is not an expression.)

Answer:

7=28² 8=

Step-by-step explanation:

7 to the power of 2 multiplied by 4 to the power of 2

= 784

$2^{5}$ × $3^{10}$ = 1,889,568

8. How much energy does a 12 V battery in your car use to move 2.5 C through the electrical

I am Lyosha [343]

The energy required is 30 watts second.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or eliminated.

The voltage of a battery is 12 V and;

The charge is 2.5C.

Now, energy can be defined as the product of voltage and charge.

Therefore,

E = V × C

E = 12 × 2.5

E = 30 watt second

Hence, the energy needed by the 12 V battery to move 2.5 C through the electrical circuit is 30 watts second.

Karolina [17]

The correct statement about the earthquake in the state is option c. State A had approximately 3,362 more earthquakes than State B.

<h3>How to solve for the earthquake in the state A</h3>

we have x/y = 0.00299

y = 163696

To solve for x we have

163696 * 0.00299

= 4895 earthquakes

<h3>Next we have to solve for earth quakes in state B</h3>

x = 0.1402 x 10931

= 1533

Next we have to find the difference

4895 - 1533 = 3362 earthquakes.

We have to conclude that state A has 3362 earthquakes more than B. Hence the answer is c.
