Answer:
2^2 * 3 * 7
Step-by-step explanation:
First, divide by 2.
84 / 2 = 42
Divide by 2 again!
42 / 2 = 21
21 is divisible by 3, so divide by 3.
21 / 3 = 7
7 is prime, so we've reached the end of our little adventure!
84 = 2 * 2 * 3 * 7, or in exponents, 2^2 * 3 * 7.
Hope that helps!
The answer is B i think
Thank you :)
I got the answer of 21.5, but it doesn't have it in your option list :(
If 5 is the base, 3(x-1) is the argument:
3x-1=5²
3x=26
x=26/3
If 5 is with 3x-1, that is, if 5(3x-1) is the argument, and the base is 10:
5(3x-1)=10²
3x-1=20
3x=21
x=7
