I apologize for the incorrect answers provided. The correct way to multiply numbers in scientific notation is to first multiply their coefficients and then add their exponents. Applying this to the given numbers, we get:
(1.7 x 10^1) x (7 x 10^5) = (1.7 x 7) x 10^(1+5) = 11.9 x 10^6
This result can be written in scientific notation as 1.19 x 10^7. Therefore, the answer is not among the options provided.
what is (1.8*10^1)(7*10^5) in scientific notation
To multiply numbers in scientific notation, we first multiply their coefficients and then add their exponents. Applying this to the given numbers:
(1.8 x 10^1) x (7 x 10^5) = (1.8 x 7) x 10^(1+5) = 12.6 x 10^6
Since 12.6 is between 1 and 10, we can write the answer in scientific notation as:
1.26 × 10^7
Therefore, (1.8*10^1)(7*10^5) is approximately equal to 1.26 x 10^7.
what is (1.7∙10^-4)(5 ∙ 10^-5) in scientific notation
To multiply numbers in scientific notation, we first multiply their coefficients and then add their exponents. Applying this to the given numbers, we get:
(1.7 x 10^-4) x (5 x 10^-5) = (1.7 x 5) x 10^(-4-5) = 8.5 x 10^-10
Since 8.5 is between 0 and 1, we can write the answer in scientific notation as:
8.5 × 10^-10
Therefore, (1.7∙10^-4)(5 ∙ 10^-5) is equal to 8.5 x 10^-10 in scientific notation.
what else is it equal to
We can also write 8.5 x 10^-10 in decimal notation as:
0.00000000085
So, (1.7∙10^-4)(5 ∙ 10^-5) is equal to both 8.5 x 10^-10 and 0.00000000085.
what else
There is one more way to express the result (1.7∙10^-4)(5 ∙ 10^-5), using the fact that we can rearrange and associate exponents:
(1.7∙10^-4)(5 ∙ 10^-5) = (1.7 x 5) ∙ 10^(-4 - 5) = 8.5 ∙ 10^-9
So, another way to write the multiplication (1.7∙10^-4)(5 ∙ 10^-5) in scientific notation is 8.5 x 10^-9.
