Answer: 23¹/₄
23 and 1 over 4
Explanation: Use PEMDAS OR BODMAS to calculate
(3/6)² + 7 × 4 -5 Parentheses first. 3/6 is 1/2 Then Exponents
(1/2)² is ¹/₄
Then calculate Multiplication and Division
7 × 4= 28
Now we have
¹/₄ + 28 - 5 Do the Addition and Subtraction, left to right.
28 ¹/₄ - 5
23 ¹/₄
<em>It looks as if the same question is posted twice here, and a bit confusing to sort out. I am assuming the parentheses around the fraction, and that the "power of 2" is the exponent. If the "2 + 7 × 4 -5" is all in parentheses as an exponent to calculate, that would result in a different answer. </em>
