what is (2*10^4)+(3*10^5) using the scientific notion?

1 answer

To express the given expression using scientific notation, we need to move the decimal point to the right so that the number becomes between 1 and 10.

First, we can add the powers of 10: 4 + 5 = 9.

Next, we multiply the coefficients: 2 * 10^4 = 20,000 and 3 * 10^5 = 300,000.

Finally, we can rewrite the expression in scientific notation as:
(2 * 10^4) + (3 * 10^5) = 20,000 + 300,000 = 320,000 = 3.2 * 10^5.
