Answer:
it's A
Step-by-step explanation:
Answer:
The answer is A.
You are dividing by 8, not 10.
When you are multiplying 2 numbers with exponents, you need to add the exponent. When you multiply an exponent with an exponent, you multiply them.
So,
(3^2 x 7^4) ^9
First multiply the base and add exponents = ( 21^6) ^9
= 21 ^6x9
21^54
The same rule applies for variables, just pretend there is an imaginary 1.
The correct answer is; 14x +4
(2,0) and (-1/2,0) is the correct answer
