Dominic would be the answer because the exponents add together
Lemur [1.5K]3 years ago
7 0

Answer:  Dominic,  5⁵ · 5² = 5⁷

5⁵ means 5×5×5×5×5, five factors of 5.

5² means 5×5, two factors of 5.

When we multiply these together we get 7 factors of 5:

5⁵ × 5² = (5×5×5×5×5)×(5×5) = 5×5×5×5×5×5×5 = 5⁷

Multiplication of powers of a common base are simple; we keep the base and add up the exponents to get the exponent of the product.

Vanyuwa [196]

Answer:

(-3)^2

Step-by-step explanation:

You add 7 on both sides, giving you x^2 - 6x = 7

Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7

The answer will be (-3)^2 for this question, but this is not the full solution.

Hope this helped. Good luck on the rest!
