$3\times 5^2÷15-5+2^2$

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is C 4

Given mathematical expression,
$3\times 5^2÷15-5+2^2$
Solving the exponents,
= $3\times 25÷15-5+4$

The expression contains both multiplication and division operations.
$\therefore$ According to PEMDAS, operations of multiplication and division are to be solved from the left.

= $75÷15-5+4$
= $5-5+4$

The expression contains both addition and subtraction. So, we have to solve both operations in the expression from the left.

= 0 + 4
= 4
