Question

Find the value of x ......
Please answer this question..... ​

Answer 1

x=5/2

Explanation:

(2/7)^2x *(2/7)=(2/7)^6

(2/7)^(2x+1)=(2/7)^6

Equate indices

2x+1=6

2x=6-1

2x=5

x=5/2

Answer 2

When multiplying the same number, raised to different powers, you carry the number forward so (2/7)^6 is part of the answer.

Now, we have to calculate the exponent.

2x + 1 = 6

So, the answer is x = 2.5 which means

[2/7]^(2*2.5) x [2/7]^1 = [2/7]^6 which equals

[2/7]^5 x [2/7]^1 = [2/7]^6
