Answer:
5
Step-by-step explanation:
(I'm assuming that by m2 and n2 you mean m to the power of 2 and n to the power of 2)
Whenever you have a number to a power, it is the same as that number times itself that power number of times. For example, 3 to the power of 4 is equal to 3 times itself 4 times, which is 3 * 3 * 3 * 3. If we use this and substitute the values in for m and n, we get that 3^2 - 2^2, and since 3^2 is 3 * 3 and 2^2 is 2 * 2 and 3 times 3 is 9 and 2 times 2 is 4, we get that 9 - 4 is 5.
<em>Note: This symbol means to the power of ----> ^</em>
(6^-2 * 6^5)^-3
Raise each term by -3:
(6^-2)^-3 * (6^5)^-3 =
6^6 * 6^-15
Rewrite the second term using the negative exponent rule:
6^6 * 1/(6^15)
Subtract the exponents
15-6 = 9
The answer is 1 / 6^9 ( The second answer)
Answer: the answer is 1020
Step-by-step explanation: Because lets say 1032-133=899
so if we do 899+121=1020
