Is there any way to solve this type of inequality (x+3)^3(x+1)^2.5 >0

OpenStudy (anonymous):

we can't solve this using normal method

ganeshie8 (ganeshie8):

\(a\)\(b\) > 0 requires both \(a\) and \(b\) be of same sign

ganeshie8 (ganeshie8):

oh you're looking for some fast way is it...

OpenStudy (anonymous):

no not a fast way actually but i don't know if it is possible to find the sollutions when when component is raised to a decimal like 2.5

OpenStudy (anonymous):

they aren't whole numbers

OpenStudy (anonymous):

@ganeshie8

OpenStudy (nipunmalhotra93):

you could split 2.5 into 2 + 1/2

OpenStudy (anonymous):

(x+1)^2(x+1)^0.5 like that

OpenStudy (nipunmalhotra93):

Yeah.

OpenStudy (anonymous):

so what about the 1/2 raised power how do we solve that then

OpenStudy (nipunmalhotra93):

square root is always positive.

OpenStudy (nipunmalhotra93):

However, you'll get a restriction on the domain for x i.e x>-1 as x+1>0 (because sqrt of negative numbers in complex)
