Answer 1

Complete Question

Joey tried to evaluate an expression. Here is his work:

= 97– 3 + (5³÷25)× 2 × 3²

= 97–3 + (125÷25 )× 2 × 9

Step 1 = 97 – 3 + 5 × 2 ×9

Step 2 = 97 – 3+ 10×9

Step 3 = 97 – 3+ 90

Step 4 = 97–93

Step 5 = 4

Step 6 = Is Joey's work correct?

Answer:

Joey's work is incorrect

The correct answer is 184

Step-by-step explanation:

Solving Joey's expression above using the BODMAS Rule

B - Bracket

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

= 97– 3 + (5³÷25)× 2 × 3²

= 97–3 + (125÷25 )× 2 × 9

Hence:

Step 1: Division

= 97 – 3 + 5 × 2 ×9

Step 2: Multiplication

= 97 – 3+ 10×9

Step 3: Addition

= 97 – 3+ 90

= 97+ 87

Step 4 :

= 97+ 87

Step 5 = 184

Therefore, Joey's work is INCORRECT because he made a mistake in Step 3 during the addition step. The correct answer is 184
