Question 1207324


{{{(5x^3(2x)^2)/(20x^4)}}} if {{{x}}} ≠ {{{0}}}


{{{(5x^3(2x)^2)/(20x^4)}}}

={{{(5x^3*4x^2)/(20x^4) }}}

={{{(20x^5)/(20x^4) }}}

={{{(cross(20)x^(cross(5)1))/(cross(20)cross(x^4)) }}}

={{{x}}}



{{{3^(x+2) = 27}}}.......{{{27=3^3}}}

{{{3^(x+2) =3^3}}}....if base same, exponents are same too

{{{x+2=3}}}

{{{x=3-2}}}

{{{x=1}}}
