Question

find the value of T if the value of 2 x power 2 minus x minus 3 is equal to 5 when x is equal to zero​

Answer 1

Step-by-step explanation:

5^x-3.  3^2x-8 = 225

                 = 3 × 75 

                 = 3 × 3 × 25 

                 = 3 × 3 × 5 × 5

∴ 5^x-3.  3^2x-8 = 5^2 × 3^2

Comparing both the sides we get

x − 3 = 2

⇒ x = 5  (You can compare even the other one also. The result will be same)
