R could equal any number, but it has to be higher than 4, because 3+4=7.
91, 168 are the answers I believe because 91 can't be made except by multiplying itself by one and 168 can be divided evenly by twelve
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.
Answer:
b
Step-by-step explanation:
2(3)(2) + 2(4)(3) + 2(4)(2)
2(6) + 2(12) + 2(8)
12 + 24 + 16
52
Hope this helps!
