Find the third term in the expansion of ...

Find the third term in the expansion of `(1-2x)^(3//2)""dot`

Text Solution

Verified by Experts

We have,
`(1-2x)^(3//2) = 1+(3)/(2) (-2x)+((3)/(2) xx 1/2)/(2!) (-2x)^(2)`
`+ ((3)/(2)xx1/2(-1/2))/(3!) (-2x)^(3)+"….."`
Hence , the `4^(th)` term is `x^(3)//2`.
