Question

3.76x10^5 + 7.44x10^5

why is it 1.12 I've been trying but I don't understand can someone go into detail why
​

Answer 1

Answer:

1.12 × $10^{6}$

Step-by-step explanation:

Given the addition of the following scientific notations:

(3.76 × $10^{5}$ ) + (7.44 ×  $10^{5}$ )

3.76 + 7.44 = 11.2

(11.20 × $10^{5}$ )  

You will have to move the decimal point one place to the left, in order to express it properly in scientific notation:  

1.12 × $10^{6}$
