Given the numerical equation:
3^(3)•4-(48-3)/5^(2)-18
Solve.
Solution:
In order to solve the given numerical equation, we simply need to apply the rules of PEMDAS, which means to start with the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. In our case we apply the PEMDAS on the numerator and the denominator first before dividing completely.
= 3^(3)•4-(48-3)/5^(2)-18
= (9)(4) - (45)/25 - 18
= 36 - 45/7
= -11/7
Final answer:
= -11/7
