Final answer:
To evaluate the expression 1.64*10⁰-:2.0*10², first simplify 1.64*10⁰ to 1.64, then simplify 2.0*10² to 200. Finally, divide 1.64 by 200 to get the result.
Step-by-step explanation:
To evaluate the expression 1.64*10⁰-:2.0*10², we can simplify it step by step.
First, let's simplify 1.64*10⁰. Any number raised to the power of 0 equals 1, so 1.64*10⁰ equals 1.64.
Next, let's simplify 2.0*10². Any number multiplied by 10 raised to the power of 2 equals the number multiplied by 100. So, 2.0*10² equals 200.
Finally, we can divide 1.64 by 200 to get the result. The answer is 0.0082.
