Question

Find the value of x question no. 1 and 4

Answer 1

Heya mate... Here's your answer
Question 1....
${ \frac{3}{4} }^{2x + 1} = { \frac{3}{4} }^{9}$
So, 2x+1=9(Because the base is same i.e.3/4)
2x=9-1
2x=8
Therefore x=4

Question 4...
This question can be written as...
${ \frac{1}{2} }^{4} \times { \frac{1}{2} }^{2} = { \frac{1}{2} }^{3(x - 2)}$
So same as question 1,
4+2=3(x-2)
6=3(x-2)
2=x-2
Therefore, x=2+2=4
Hope it helps...!
