Question

Someone pls help me answer this pls

Answer 1

Answer:

5^15

Step-by-step explanation:

Using the laws of powers, you can multiply 5^3 out of its bracket and get 5^27. Then, once again, using the laws of powers, you can get 5^15 by subtracting the powers.

Answer 2

Answer:

(5^3)^9/5^12 is equivalent to 5^15

Step-by-step explanation:

Begin by simplifying (5^3)^9

To make it much easier, apply the power rule. (a^x)^y = a^xy)

Multiply 3 x 9 = 27... so we get 5^27

Next, instead of dividing 27/12, which will result in a decimal..you must do 27-12, which is applying the quotient rule.  (a^x / a^y = a^x-y)

5^27/5^12 = 5^27-12 = 5^15

( When I use /, it signifies to divide.)

So,  (5^3)^9/5^12 is equivalent to 5^15! Hope this helps! :D
