Answer:
Solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24
Step-by-step explanation:
We need to solve the equation [tex](5^2 -4) \cdot 2 -18[/tex]
We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.
First we will solve the bracket
[tex](5^2 -4) \cdot 2 -18\\=(25-4) \cdot 2-18\\=21 \cdot 2-18[/tex]
Now multiply 21 by 2
[tex]=42-18[/tex]
Now subtract
[tex]=24[/tex]
So, solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24
