Subtract 4.66×10−^5−7.34×10−^7

1 answer

To subtract these two numbers in scientific notation, we need to have the same exponent.

Given:
4.66×10^(-5)
7.34×10^(-7)

To get the same exponent, we can convert the second number to scientific notation with the same exponent.

7.34×10^(-7) can be written as:
0.0734×10^(-5)

Now we can subtract the two numbers:

4.66×10^(-5) - 0.0734×10^(-5)

To subtract, we subtract the numerical parts and keep the exponent the same:

= (4.66 - 0.0734) × 10^(-5)

= 4.5866 × 10^(-5)

So, 4.66×10^(-5) - 7.34×10^(-7) = 4.5866 × 10^(-5)
