Answer: (2r)⁸ or (2r)∧8
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Double r = this means that we have to multiply the variable "r" by 2 .(2r)
Then raise the result to the 8th power = this means that the product (2r) is the base and 8 is the exponent.
Mathematically speaking
(2r)⁸ or (2r)∧8

Answer:35,585
Step-by-step explanation:
3x5 -3 = 12
5x12 -5 = 55

Answer:
0
Step-by-step explanation:
<u>Step 1: Make common denominators</u>
What is the LCM of 21 and 7: 7
So, we need to convert both fractions into a 21 denominator.
<em>15/21 * 1/1 = 15/21</em>
<em>5/7 * 3/3 = 15/21</em>
<em />
<u>Step 2: Subtract the numbers</u>
15/21 - 5/7 is same as 15/21 - 15/21
15/21 - 15/21
<em>0</em>
