Chapter 1: Problem 3

Evaluate each expression using order of operations. a. \(17 \cdot(52-2)\) b. \((90-7) \cdot 5\)

Short Answer

Expert verified
Answer: a. 850 and b. 415

Step by step solution

01

a. Evaluate the expression \(17 \cdot (52 - 2)\)

Step 1: Parentheses First, we need to solve the operation inside the parentheses which is the subtraction. \(52 - 2 = 50\) Step 2: Multiplication Now, multiply the result obtained in step 1 by 17. \(17 \cdot 50 = 850\) So, the answer to expression a is 850.
02

b. Evaluate the expression \((90 - 7) \cdot 5\)

Step 1: Parentheses First, we need to solve the operation inside the parentheses which is the subtraction. \(90 - 7 = 83\) Step 2: Multiplication Now, multiply the result obtained in step 1 by 5. \(83 \cdot 5 = 415\) So, the answer to expression b is 415.
