-3
form.
0.0004 +0.005 0.0054
0.00004 +0.0005 0.0054

Answer 1

To find the sum of 4 x 10-4 + 5 x 10-3, convert both numbers to the same exponent and add them together.

Step-by-step explanation:

To find the sum of 4 x 10-4 + 5 x 10-3, we can first convert both numbers to the same exponent. We can write 4 x 10-4 as 0.0004 (since moving to the right of the decimal point shifts the exponent to a more positive value) and 5 x 10-3 as 0.005 (using the same logic). Now, we simply add the two numbers together to get 0.0054.
