please help me solve
Multiply and simplify type exponential notation with positive exponents
(64a^2)/(2a^216a+32) x (2a8)/8a

( a  4 ) ^ 2 = a ^ 2  2 * a * 4 + 4 ^ 2 = a ^ 2  8 a + 16
2 a ^ 2 1 6 a + 32 = 2 * [ ( a  4 ) ]^ 2
( 64 a ^ 2 ) / ( 2 a ^ 2  16 a + 32 ) * ( 2 a  8 ) / 8 a =
( 64 a ^ 2 / 8 a ) * ( 2a  8 ) / 2 * [ ( a  4 ) ] ^ 2 =
8 a * ( 2 a  8 ) / [ 2 * [ ( a  4 ) ]^ 2 =
[ 8 a * 2 ( a  4 ) ] / [ 2 * [ ( a  4 ) ]^ 2 =
[ 8 a * 2 ( a  4 ) / 2 ] / [ ( a  4 ) * ( a  4 ) ] =
8 a / ( a  4 )
