Answer:

13.5

Explanation:


3*(7+2)/√(4)

You use PEDMAS - priority of calculation

1) Paranthesis

2) Exponents

3) Divide or Multiple (whichever comes first, reading left to right)

4) Add or Subtract (whichever comes first, reading left to right)

so,

Parenthesis first:


7+2=9

becomes


3*9/√(4)

No exponents, so we skip this step

Left to right for multiply or divide: first comes multiply.


3*9 = 27

becomes


27/√(4)

Now, last one is divide:


27/√(4) = 27/2 = 13.5

using podmas rule:

  • P - parenthesis
  • O - Order
  • D - Division
  • M - Multiplication
  • A - Addition
  • S - subtraction

==============


\dashrightarrow \sf 3 * (7+2) \ / \ √(4)


\dashrightarrow \sf 3 \ * \ 9\ / \ √(4)


\dashrightarrow \sf 3 \ * \ 9\ / \ 2


\dashrightarrow \sf 3 \ * \ 4.5


\dashrightarrow \sf \ 13.5
