Question

(10^3 X 10^2) + 10^-3=

Answer 1

(10^3 x 10^2) + 10^-3 is equal to 100,000.001.

Explanation:

10^3 x 10^2 = 10^(3+2) = 10^5

Next, we perform the multiplication:

10^5

Finally, we add the value of 10^-3:

10^5 + 10^-3

Now, we have two numbers in scientific notation. To add them, we need to make sure they have the same exponent.

10^5 can be written as 100,000 in standard notation.

10^-3 can be written as 0.001 in standard notation.

Now, we can add them:

100,000 + 0.001 = 100,000.001

Answer 2

100000.001

Explanation:

To simplify this expression, you can use the properties of exponents.

• First, let's simplify the multiplication of the powers of 10:

10³ × 10² = 10²⁺³ = 10⁵

• Now, let's add 10⁻³ to the result:

10⁵ + 10⁻³

• So, the final answer is:

10⁵ + 10⁻³ = 100000 + 0.001 = 100000.001
