Answer is 5^12 which is choice A (assuming you meant to put the ^ symbol)

The bases are the same (both are 5), so you add the exponents: 4+8 = 12. The base stays the same the entire time.

So, 5^4*5^8 = 5^(4+8) = 5^12

Solve this question <br>a=7+3​
mr Goodwill [35]

Answer:

<h2>10</h2>

Step-by-step explanation:

<em>The answer is 10 because 7 + 3 equals 10!</em>

<em></em>

<em>This can be proven by adding 7 + 3 or by subtracting in a certain way.</em>

<em>7 + 3 = ?</em>

<em>7 + 1 = 8</em>

<em>7 + 2 = 9</em>

<em>7 + 3 = 10</em>

<em></em>

<em>You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.</em>

<em></em>

<em>If you subtract 7 by 10, ( 10 - 7 ) then you get 3</em>

<em>If you subtract 3 by 10, ( 10 - 3 ) then you get 7</em>

<em>If the number you subtracted matches the number that you didn't subtract, then your answer is correct.</em>

<em></em>

<em>Hope this helps! <3</em>

Kisachek [45]

Answer:

First blank: 4

Second blank: 3

Third blank: 8

Step-by-step explanation:

The expressions must be equivalent, yet one must read as 4 times the length of the box.

Looking at the given expression, 12x + 32, both numbers can be evenly divided by 4.

Since the blank spaces contain parenthesis, I can assume the problem is asking us to factor the numbers.

This means we put the number 4 on the outside of the parenthesis to display "4 times the side length."

4 × ? = 12

4 × 3 = 12

Substitute 12 for 3.

4 × ? = 32

4 × 8 = 32

Substitute 32 for 8.

4 (3x + 8)
