Which expression is equivalent to 7 to the 3 power × 7 to the −5 power

A: 72

B: 77

C: 1 over 7 to the 2nd power

D: 1 over 7 to the 7th power

C: 1 over 7 to the 2nd power

Step-by-step explanation:

The question is:

When multiplying exponents, the base stays the same, while the power is added. In this question, the powers are 3 and -5.

The exponent will become:

Since the power is negative, it is improper. The negative can be removed by moving the power down and making it a fraction over 1.

The answer is , also written as "1 over 7 to the 2nd power".

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
