hi there, please consider the following step to get you started.
Now square every term inside the bracket then simplify.
How do I solve/simplify this:
((2a^-2 b^4) / (4a^3 b^-2))^-2
Do I do the ^-2 to everything inside first? Or what steps do I do first?
And how do I factor this:
I don't remember completely as I haven't done it in years, but it has to add up to -7 and multiply together to 12? Or something along those lines...
Any help would be great, thanks.
