Question

How do you solve this problem in the photo?

Answer 1

Answer: 5^2

Step-by-step explanation:

Since the base are all the same, you will add the exponents and let the exponents stay the same.

5^3  * 5^4= 5^7 * 5^-5= 5^2

Answer 2

Answer:

25

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

The rule can be extended to include more than 3 terms.

Given

5³ × $5^{4}$ × $5^{-5}$

= $5^{(3+4-5)}$

= 5²

= 25
