9 to the power 3 + 3 to the power 2 + 6 to the power 3 + 15 power 2 equals to how much

Llana [10]

Hey! So, here's a tip. When writing exponents, an easier way is to write a^b, rather than a to the b power. Besides that, here is your answer!

So-------

9^3=729

3^2=9

6^3=216

15^2=225

Now that we have that figured out, we can add them together, wish is simple. 729 + 9 + 216 + 225= 1,179.

Therefore, your final answer will be 1,174.

If you have any questions on this, I'm happy to help you. :)

Jamie can read at a speed of 65 pages per hour. If she reads a novel that has 400 pages, how long will it

horsena [70]

To find the answer set up an equation:
$400 \: pages \times \frac{1 \: hour}{65 \: pages} =$
Using this set up we can cross our units of pages since they are on opposite side of the proportion, leaving us with the desired units of hours.

Then divide 400 by 65 which will give us our answer: 6.15 or about 6 hours for Jamie to finish her reading.
