#"using the "color(blue)"laws of exponents"#
#•color(white)(x)a^mxxa^nhArra^((m+n))# #•color(white)(x)a^m/a^n=a^((m-n))
#•color(white)(x)a^(1/2)hArrsqrta#
#•color(white)(x)a^(m/n)hArrroot(n)(a^m)#
#"the form "f(x)=kx^plarrcolor(blue)"k is a constant"#
#(a)#
#R(t)=4/sqrt(16t)=4/(sqrt16xxsqrtt)=4/(4t^(1/2))=1t^(-1/2)#
#(b)#
#T(s)=(6s^-2)(4s^-3)=6xx4xxs^((-2-3))=24s^-5#
#(c)#
#K(w)=(w^4)/(4sqrt(w^3))=(w^4)/(4w^(3/2))=1/4w^((4-3/2))=1/4w^(5/2)#
