Ok, so we have
$${\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right)}^{{\mathtt{2}}}$$
Something raised to the second power really just means times itself two times, right?
Here's an example:
52 = 5*5 = 25
So, back to our question. We really just have to multiply 3/4 times 3/4!
$$\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right)$$
Multiply the top and bottoms
$${\frac{{\mathtt{9}}}{{\mathtt{16}}}}$$
or
$${\mathtt{0.562\: \!5}}$$
And there we go! 3/4 to the second power is 9/16 or 0.5625.
