The answer is 40, 2^3=8 2^5=32, so 32+8=40
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
225
Both are correct.
3^2 x 5^2 = 3 x 3 x 5 x 5 = 9 x 25 = 225
It is correct only for the first one. The second one should be 3 to the power 2 times 2 times 5.
(2 * 3)^2 *5=180 but 2*(3)^2 *5=90
-2
2^5 x 2^3 = 2^8 = 256
225
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.
120
It is 12400, if i did the math right.
