What is the value of the expression below?

32+53−25

F. 14

G. 34

H. 102

J. 166


Short Answer

Expert verified

The value of the expression is option H. 102.

Step by step solution

01

Step 1. State the concept of DODMAS Rule.

BODMAS is a short form for Brackets, order of power, Division, Multiplication, Addition and Subtraction.

This rule explains the order of operations (order of precedence) to solve an expression.

02

Step 2. Evaluate the exponents.

Evaluate the values of 32,53and 25.

32=3×3=953=5×5×5=12525=2×2×2×2×2=32

03

Step 3. Find the value of the given expression.

Substitute the above values in the expression and simplify further.

32+53−25=9+125−32=134−32=102

Therefore, option His the correct answer.
