a to the power b:
a^b, ^ is called a cap and typed using "shift 6" in most keyboards.

m tag:
a^b

-1 to the power m+n

(-1)^(m+n)
m tag:
(-1)^{(m+n)}

Answer : 25^sqrt{2}
(5^sqrt{2})^2 = 5^ sqrt{2} * 5^ sqrt{2}
= 5^ sqrt{2}
= 25^ sqrt{2}

B is the answer. Tricky one but remember that the exponents will multiply each other, giving you 5^(2root2).

Cheers.

a^b^c is a^(b^c) and not a^bc.So ,root(2)^2=1.9946~2;5^2=25

The answer is B. (5^sqrt{2})^2 = (5^2)^sqrt{2} = 25^sqrt{2} :)
