Question 293403
It's not an equation.  All equations have an equal sign.
There are 3 variables, you didn't say which one to solve for, but since it's not an equation, it can't be solved anyway.
-----------------
{{{ ((8x^6 +(3*10^7)(2*10^-5)) / ((5y+2)(2w)))^2 }}}
It can be simplified some.
= {{{ ((8x^6 + 600) / ((5y+2)(2w)))^2 }}}
= {{{ ((4x^6 + 300) / ((5y+2)(w)))^2 }}}
--------------
From there it can be expanded, but that's not simplification.
= {{{(4x^6 + 300) / (5wy+2w))^2 }}}
= {{{(16x^12 + 2400x^6 + 90000)/(25w^2y^2 + 20w^2y + 4w^2)}}}
The 16 can be factored out:
= {{{16(x^12 + 150x^6 + 5625)/(25w^2y^2 + 20w^2y + 4w^2)}}}
All versions are equal.
Simplification can be a matter of opinion.
