Subtract 4.66×10^-5 -7. 34×10.^-7

3 answers

To subtract these numbers, we need to ensure that the exponents of the numbers are the same.

First, let's rewrite the numbers in scientific notation:
4.66×10^-5 = 0.0000466
7.34×10^-7 = 0.000000734

Subtracting these two numbers gives:
0.0000466 - 0.000000734 = 0.000045866

So, the result is 0.000045866.
Subtract 4.66×10^-5 -7. 34×10.^-7

A. 4.5866 x10^-5
B. -2.68 x 10^2
C. 2.68 x 10^2
D. -4.5866x10^-5
Apologies for the previous response. Let's calculate the subtraction correctly:

4.66 × 10^-5 - 7.34 × 10^-7

To subtract these numbers, we need to ensure that the exponents of the numbers are the same.

4.66 × 10^-5 = 0.0000466 (after converting from scientific notation)
7.34 × 10^-7 = 0.000000734 (after converting from scientific notation)

Now, subtracting these two numbers gives: 0.0000466 - 0.000000734 = 0.000045866.

Converted back to scientific notation, this is equal to 4.5866 × 10^-5.

So, the correct answer is option D: -4.5866 × 10^-5.
