A =[ ( 4 ⁻² x 8 ⁴ ) / ( 90 ⁷ x 30 ⁻² ) ] ³
A = [ ( 2²) ⁻² x (2³)⁴ ) / ( 2 x 3² x 5 ) ⁷ x ( 2 x 3 x 5 ) ⁻² ] ³
A = [ ( 2 ⁻⁴ x 2 ¹² ) / ( 2 ⁷ x 3 ¹⁴ x 5 ⁷ x 2 ⁻² x 3 ⁻² x 5 ⁻² ) ] ³
A = [ ( 2 ⁻⁴ x 2 ¹² ) /(2 ⁵ x 3 ¹² x 5 ⁵ )] ³
A = [ 2 ⁸ / 2 ⁵ x 3 ¹² x 5 ⁵ ]³
A = ( 2 ³ / 3 ¹² x 5 ⁵ ) ³
A = 2 ⁹ / 3 ³⁶ x 5 ¹⁵
B = [ ( 3²)³ x ( 2⁴)⁴ ) / ( ( 5²)² x 2 x 3² x 5 ) ⁻² ] ²
B =[ ( 3 ⁶ x 2 ⁸ ) / ( 5 ² x 2 ⁻² x 3 ⁻⁴ x 5 ⁻² )] ²
B = [ 3⁶ x 2 ⁸) / ( 2 ⁻² x 3 ⁻⁴ x 5 ⁰) ]²
B = ( 2 ¹⁰ x 3 ¹⁰ ) ²
B = 2 ²⁰ x 3 ²⁰
