It is correct only for the first one. The second one should be 3 to the power 2 times 2 times 5.
2^5 x 2^3 = 2^8 = 256
Both are correct.
3^2 x 5^2 = 3 x 3 x 5 x 5 = 9 x 25 = 225

(2 * 3)^2 *5=180 but 2*(3)^2 *5=90
-2
2^5 x 2^3 = 2^8 = 256
360
Both are correct.
-5
3^2 x 5^2 = 3 x 3 x 5 x 5 = 9 x 25 = 225
8 x 9 x 5 and 4 x 3 x 25 360 and 300 The GCF is 60.

5 to the power of three times 5 to the power of 2 is equal to 5 to the power of 5. We know this because A^a times A^b equals A^(a+b). We know this by solving the problem manually. 5 to the power of 3 is equal to 5*5*5 and 5 to the power of 2 is equal to 5*5. when you multiply them, it becomes 5*5*5*5*5 which is equal to 5 to the power of 5.
It is 12400, if i did the math right.
