How do I solve (2x^3)^4?
larisa86 [58]
Hello There!

You would have to do work out 2 to the fourth power.
Also, 3 x 4.
The rules of powers are:
If you have to multiply, you add them
If you have to divide, you subtract them
If they are in brackets like this ^^, you multiply them.

Therefore, your answer is 16^{12}

Hope This Helps You!
Good Luck :)

One number is six times another number. Their difference is 35. What are the two numbers?
konstantin123 [22]









x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
