To evaluate this expression, you should use the order of operations (PEMDAS: Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) to simplify it step by step.
Let's break it down:
1. First, we have the exponent 3^2. Evaluating this exponent, we get 9: 3^2 = 3*3 = 9.
2. Next, we multiply: 1/2 * 4 = 2.
3. Finally, we subtract: 2 - 9 = -7.
So the expression simplifies to -7.

What is the exponent in the exponential form of the expression (1/8)(1/8)(1/8)
In the expression (1/8)(1/8)(1/8), each factor (1/8) represents the base raised to the power of -1.
When multiplying fractions, the exponents are summed.
So, in the given expression, we can rewrite it as (8^-1)(8^-1)(8^-1).
When multiplying the bases with the same exponent, we add the exponents together.
Therefore, we can simplify the expression to 8^(-1 + -1 + -1) = 8^(-3).
The exponent in the exponential form of the expression (1/8)(1/8)(1/8) is -3.
