    \(\large (x^y)^z)=x^{y*z}\) using this can u simplify \(\large (b^3)^2\)?

    wait a sec. oops sorry it is \(\Large (-2x^2)^3\) right? So \(\Large (-2x^2)^3=(-2)^3*(x^2)^3\) We r nt yet done with our previous problem. so it will be better if we finish that and come to this one. What is \((-2)^3)? What do u get when u simplify \((x^2)^3\)?

    ya:) so \(\Large (-2x^2)^3=-8x^6\) Nw \(\Large(-4xy)^3=(-4)^3*(x^1)^3*(y^1)^3\) What is \(\Large (-4)^3=\)? What do u get when u simplify \(\Large (x^1)^3\) and \(\Large (y^1)^3\)?

    \(\Large(a^b)^c=a^{b*c}\) usin this general rule only u have to simplify \((x^1)^3\) and \((y^1)^3\)

    \(\Large(-4xy)^3=-64x^3y^3\) \(\Large(-2x2)^3=-8x^6\) \(\Large(-64x^3y^3)*(-8x^6)=(-64*8)*(x^3*x^6)*y^3\) To simplify \(\Large(x^3*x^6)\) u have to use the general rule \(\Large(a^b)*(a^c)=a^{b+c}\)

    k nw moving on to ur next problem \[(-14xy^4)(\frac{ -1 }{ 2 }xy^3)=(-14*-\frac{ 1 }{ 2 })(x^1*x^1)*(y^4*y^3)\] See if u can simplify nw. If u find any difficulties while solving pls do ask:)
