simplify the expression below using order of operations.
(6 + 9^1) × 10 − 3^2

Explanation:

Step1: Simplify exponents

First, handle the exponent \(9^1\). By the definition of exponents, any number to the power of 1 is itself, so \(9^1 = 9\). Also, simplify \(3^2\), which is \(3\times3=9\). The expression becomes \((6 + 9)\times10 - 9\).

Step2: Simplify parentheses

Next, simplify the expression inside the parentheses: \(6 + 9 = 15\). Now the expression is \(15\times10 - 9\).

Step3: Perform multiplication

Then, perform the multiplication: \(15\times10 = 150\). The expression is now \(150 - 9\).

Step4: Perform subtraction

Finally, subtract: \(150 - 9 = 141\).

Answer:

141
