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. :)

<u>Pre-Calculus</u>

Circle Center Formula: (x - h)² + (y - k)² = r²

  • <em>(h, k) </em>is center
  • <em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em>(h, k)</em> = (8, 10)

<em>r</em> = 6

<u>Step 2: Find Equation</u>

  1. Substitute in variables [Center Circle Formula]:                                             (x - 8)² + (y - 10)² = 6²
  2. Evaluate exponents:                                                                                         (x - 8)² + (y - 10)² = 36
