Answer:
Option C
Step-by-step explanation:
(7x^3y^3)^2
= (7)^2 * (x^3)^2 * (y^3)^2
= 49 * x^(3*2) * y^(3*2)
= 49x^6y^6
You have to distribute the terms in "7x^3 * y^3" each to the power of 2
(7)^2 * (x^3)^2 * (y^3)^2
Now you can apply the rule "(x^a)^b = x^a*b" and further simplify the expression
Answer:

Step-by-step explanation:
Assuming the equation is:

Then taking antilogarithms gives:

We simplify on the left to get:

This gives us:

We subtract 3125 from both sides to get:



Answer:
B 2124
D 1416
Step-by-step explanation:
Take the ratio
A B C D Total
3 6 8 4 21 (3+6+8+4 = 21)
B gets 6 out of every 21 items
Take that fraction times the total items
6/21 * 7434 = 2124
D gets 4 out of every 21 items
Take that fraction times the total items
4/21 * 7434 = 1416
I don't really know how to explain it to you but what I can tell you is that in 1 centigram there are 10 milligrams.
The answer is 1/13, because 13 goes into 169 13 times
