Which expression is equal to 5y^3÷5y^-2

=

Step-by-step explanation:

as 5 is both in numerator and denominator it will get cancelled so we have now expression

we will use  law of indices wherein if there is

which means that if the base is same in numerator and denominator then we have to subtract the power of denominator from numerator to get the reduced form using this concept

here power in numerator is 3 and power in denominator  is -2

hence we will be subtracting -2 from 3

Thus,

=

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
