Add and subtract the values. Express your answer in scientific notation.
(5.4 times 10 Superscript 5 Baseline) + (2.9 times 10 Superscript 5 Baseline) minus (1.1 times 10 Superscript 4)
7.2 times 10 Superscript 5
8.19 times 10 Superscript 5
8.41 times 10 Superscript 5
9.4 times 10 Superscript 5
(5.4 x 10^5) + (2.9 x 10^5) - (1.1 x 10^4)
= (5.4 + 2.9) x 10^5 - 1.1 x 10^4
= 8.3 x 10^5 - 1.1 x 10^4
= 8.3 x 10^5 - 1.1 x 10^4
= 8.19 x 10^5
So the answer is 8.19 x 10^5.
