3^(x−1) = 27
I need the answer please and thanks

x=2

Step-by-step explanation:

For the given equation

To find the value of x which is in power of base 3, make the base of R.H.S also 3

Making 27 in the power of three will be written as:   27=

So,                    

Now, we have same base on both the sides, so we can equate their powers of R.H.S and L.H.S.

So, for the equation, the value of x is 2

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
