1. (Help) Finding "x" in an equation: (x-1)3/4 = 64.

I'm grade 9 doing very basic algebra, and I came across this question which I just can't figure out.
It's asking me to find the value of "x" in the equation (x-1)3/4 = 64. They haven't explained how to do this in the book and i'm home schooled so no teacher to ask. That x-1 throws me off.
Can anyone please explain how you get the answer and what steps you go through to find x? Thank you all. Hope this makes sense.

2. What would you do if it were just 'x', rather than 'x-1'? Please demonstrate.

Also, please clarify. Is that $(x-1)^{3/4}\;or\;(x-1)\cdot\dfrac{3}{4}$ or something else?

3. Can you solve:
x(3/4) = 60

Btw, x(3/4) means x multiplied by 3/4.
