Question

How do you make (9x10^9)x(-2x10^-3) true

Answer 1

Now it is true, and you have simplified the expression correctly.

Explanation:

To make the expression (9x10^9) x (-2x10^-3) true, you need to correctly perform the multiplication of these numbers. Here's how you do it:

Calculate the product of the coefficients (the numbers in front of the powers of 10): 9 x (-2) = -18.

Now, apply the rules of exponents when multiplying numbers with the same base (10 in this case). When you multiply two numbers with the same base and different exponents, you can add the exponents.

10^9 * 10^-3 = 10^(9 - 3) = 10^6

So, the expression simplifies to -18 x 10^6.

Now it is true, and you have simplified the expression correctly.
