4×10^-3
4 × 10^-3 is equal to 0.004.
To simplify 4×10^-3, we can multiply 4 with the value of 10 raised to the power of -3. This can be done as follows:
4 × 10^-3 = 4 × (1/10^3) [since 10^-3 is the same as 1/10^3]
Simplifying further, we get:
4 × (1/10^3) = 4/10^3 [applying the rule for multiplying fractions]
The value of 10^3 is 1000, so we rewrite it as:
4/10^3 = 4/1000
And finally, simplifying the fraction 4/1000:
4/1000 = 1/250 [by dividing both the numerator and denominator by 4]
Therefore, 4×10^-3 is equal to 1/250.
To calculate 4 multiplied by 10 raised to the power of -3 (4×10^-3), you can use the following steps:
Step 1: Write down the number 4.
Step 2: Take the number 10 and raise it to the power of -3. To do this, you can divide 1 by 10 cubed.
10^-3 = 1 / (10^3) = 1/1000 = 0.001
Step 3: Multiply the number 4 by the result from step 2.
4 × 0.001 = 0.004
Therefore, 4 multiplied by 10 raised to the power of -3 (4×10^-3) equals 0.004.
