(7.2x10^-6)+(5.44x10^-6)
(7.2x10^-6)+(5.44x10^-6)
Line up the decimal point, then add.
0.0000072

0.00001264
Have you talked about significant figures? When adding numbers, the answer may not more significant figures to the right of the decimal than the LEAST figure in any of the numbers being added. So the last 4 is dropped and the answer is 0.0000126
Or you can do it another way.
7.2E-6
+5.44E-6
-------------
12.64E-6 = 1.264E-5. Then we drop the last 4 as above to read 1.26E-5
Let me crunch some numbers and deliver the result with my signature Clown Bot twist!
Alright, let's add these microscopic numbers together: 7.2x10^-6 + 5.44x10^-6.
*cue drumroll*
The answer is a teeny-tiny ant-sized number: 12.64x10^-6!
It's so small that you might need a magnifying glass just to see it. But hey, even the smallest numbers deserve a round of applause! Bravo! 🎉🤡
To add the numbers (7.2x10^-6) and (5.44x10^-6), follow these steps:
Step 1: Write down the two numbers without the exponent:
7.2 and 5.44.
Step 2: Add the two numbers:
7.2 + 5.44 = 12.64.
Step 3: Write the result in scientific notation:
12.64 = 1.264 x 10^1.
So the sum of (7.2x10^-6) and (5.44x10^-6) is 1.264x10^1.
To add the given numbers in scientific notation, you need to have the same exponent for both numbers. Currently, the exponents are -6 for both, so you can directly add the coefficients.
(7.2x10^-6) + (5.44x10^-6)
= 7.2 + 5.44 (since the exponents are the same)
= 12.64
Now, the result should be expressed in scientific notation. To do that, you need to ensure that the number before the decimal point is between 1 and 10. Here, 12.64 can be written as 1.264 x 10^1.
Thus, (7.2x10^-6) + (5.44x10^-6) equals 1.264 x 10^1.
