Question

find the value of x in each case​

Answer 1

Answer:

x=2

Step-by-step explanation:

(3/4)^4 * (3/4)^5 = (3/4)^5x-1

(3/4)^4+5 = (3/4)^5x-1 [ Product law of exponents applied (a^m * a^n=a^m+n)]  

(3/4)^9 =(3/4)^5x-1

As the bases are same we can compare their exponents

9=5x-1

9+1=5x

5x=9+1

5x=10

x=10/5

x=2
