130 you multiply the left side by 13 to get the right side.
I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.
Answer:
b. 6¹⁰ / 7⁶
Step-by-step explanation:
(6⁵/7³)²
6 × 6 × 6 × 6 × 6 = 7776
7 × 7 × 7 = 343
(7776/343)²
7776²/343²
7776 × 7776 = <u>60.466.176</u>
343 × 343 = <u>117.649</u>
6¹⁰/7⁶
6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176
7 × 7 × 7 × 7 × 7 × 7 = 117.649
6¹⁰ = 7776²
7⁶ = 343²
= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>
