The value of this expression is 16. In exponential problems you can multiply the base by the number of times the exponent is. In this case it would be: 2*2*2*2. Then just multiply and get the product of 16.
You just have to go 7x28=[7x20]+[7x8]=196
Answer:
A
Step-by-step explanation:
Given
cx - 4 = 7 ( isolate the term in x by adding 4 to both sides )
cx = 11 ( divide both sides by c )
x =
→ A
