465 -(-45) = x
This creates a double negative which becomes a positive and you solution would be 465+45 =X, X = 510
Answer:

Step-by-step explanation:

A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.
This means that the fraction above could also be expressed as;

If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.
Answer:
The correct answer is 64 times Geri’s original answer
Step-by-step explanation:
Given
Gari's Answer: 2³
Correct Answer: 2⁹
Required:
Relationship between both answers
Let Gari's answer be represented by G and the Correct answer be represented by C; Such that
G = 2³
C = 2⁹
Divide C by G

From law of indices, 
Applying this law, we have




Multiply both sides by G


Hence, we can conclude that the correct answer is 64 times Geri’s original answer
