Multiply/Simplify/Expand:
(92x4)2
Use the square of a difference:
(ab)2=a22ab+b2,
where:
a=9, and b=2x4
Plug in the known values.
(92x4)2=92(292x4)+(2x4)2
Simplify 92 to 81.
(92x4)2=81(292x4)+(2x4)2
Apply the multiplicative distributive property: (ab)m=ambm
(92x4)2=81(292x4)+22(x4)2
Apply power rule: (am)n=amn
(92x4)2=81(292x4)+22x8
Simplify.
(92x4)2=8136x4+4x8
Rearrange the equation in descending order.
(92x4)2=4x836x4+81
