Answer 2

To solve the equation X × 10^(-2) = 8, you need to isolate the variable X on one side of the equation. Follow these steps:

Step 1: Divide both sides by 10^(-2) to eliminate the coefficient of X. Step 2: Perform the calculation to find the value of X.

Let's proceed with the steps:

Step 1: X × 10^(-2) = 8

Divide both sides by 10^(-2): X = 8 / 10^(-2)

Step 2: Now, recall that raising a number to a negative exponent is equivalent to taking the reciprocal of the number with a positive exponent. Therefore, 10^(-2) is equal to 1 / 10^(2) or 1 / 100.

X = 8 / (1/100)

To divide by a fraction, multiply by its reciprocal:

X = 8 * 100

X = 800

The solution to the equation is X = 800.
