1- Let's solve the numerator Inside the bracket m⁻¹.m⁵ =m⁽⁻¹⁺⁵⁾ =m⁽⁴⁾
2- numerator/denominator = m⁽⁴⁾ / m⁻² = m⁽⁴⁾⁻⁽⁻²⁾ =m⁶
3- Now let' include it in the parenthesis:[ m⁶]⁻³ =m⁻¹⁸ =1/m¹⁸<u />
B is 8 plus 3A
C is 37 plus A
A is A
A plus B plus C is 180
A plus 8 plus 3A plus 37 plus A is 180
5A plus 45 is 180
5A is 135
A is 27
B is 8 plus 3 times 27
B is 8 plus 81
B is 59
C is 37 plus 27
C is 64
