    hii @wade.ness Is your question \(\Large (x+1)^{3/2}=27 \) or \(\Large \frac{(x+1)^3}{2}=27 \)?

    (x+1) to the power of 3/2 = 27

    Okay, so what you could do first is what @Loser66 suggested, changing 27 to an exponent, so: \(\Large (x+1)^{3/2} =3^3 \) Now, to cancel the exponent multiply by it's reciprocal: \(\Large [(x+1)^{3/2}]^{2/3} =(3^3)^{2/3} \) Do you know how to multiply exponents?
