Question

What is (6•10^-13)(2.5•10^11) in scientific notation

Answer 1

The answer you are looking for is 1.5x10^1 or 0.15

Explanation:

To find the answer I used PEMDAS. (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction).

So I looked at the Parenthesis first, and then I looked for the exponents which were
`10^(-13)`, also
`10^(11)`.

When put in the calculator 0.0000000000001, and the second exponent was 100000000000.

Then having to multiply 0.0000000000001 by 6 gave me 0.00000000000006 and also multiplying 2.5 with 100000000000 gave me 250000000000.

Finally multiplying the final results with each other gave me 0.15 and in scientific notation, 1.5x10^1

I hope this was helpful!
