Question

Work out (8.2x 10*5) +(3x 10*5) give your answer in standard index form

Answer 1

To work out the given expression in standard index form, we add the coefficients and keep the same power of 10.

Step-by-step explanation:

To work out (8.2x 105) +(3x 105) in standard index form, we add the numbers and keep the same power of 10. In this case, the powers of 10 are the same, so we can simply add the coefficients:

8.2 + 3 = 11.2

Therefore, the answer is 11.2 x 105, which is the standard index form.
