300-7[4 (3+5) ]+3 to the 3rd power

The answer is 103

Step-by-step explanation:

The given expression is:

300-7[4 (3+5) ]+3 to the 3rd power

3 to the 3rd power means 3^3

Therefore,

300-7[4 (3+5) ]+3^3

First we will solve the round bracket and find the cube

300-7[4 (8) ]+27

Now we will solve square bracket

300-7[32] + 27

300-224+27

76+27

103

Thus the answer we get is 103 ...
