Answer 2

To solve the expression 11¼ - (5⁴/⁷ + 3⁶/⁷), we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Step 1: Simplify the exponents

First, let's simplify the exponents in the expression. We have 5⁴/⁷ and 3⁶/⁷.

5⁴/⁷ can be calculated as follows: 5⁴ = 5 * 5 * 5 * 5 = 625 So, 5⁴/⁷ = 625/7 = 89.2857 (rounded to four decimal places).

Similarly, 3⁶/⁷ can be calculated as follows: 3⁶ = 3 * 3 * 3 * 3 * 3 * 3 = 729 So, 3⁶/⁷ = 729/7 = 104.1429 (rounded to four decimal places).

Step 2: Perform addition and subtraction

Now, let's substitute the simplified values back into the expression and perform the addition and subtraction.

11¼ - (89.2857 + 104.1429)

To subtract the sum of the two values from 11¼, we need to convert 11¼ to a decimal. 11¼ is equal to 11.25.

11.25 - (89.2857 + 104.1429)

Next, let's add the two values inside the parentheses.

11.25 - (193.4286)

Finally, subtract the value inside the parentheses from 11.25.

11.25 - 193.4286 = -182.1786

Therefore, the solution to the expression 11¼ - (5⁴/⁷ + 3⁶/⁷) is approximately -182.1786.

Please note that the solution is rounded to four decimal places.
