Question

If √7√7√7√7√7=7^x then find the value of x

Answer 1

Answer:√7√7=7

Therefore

LHS = 7^3

Therefore x=3

Step-by-step explanation:

Answer 2

Answer:

We know, √7 × ✓7 is 7.... There are 5 √7's... So the value of the L.H.S ( left hand side) is 49√7

So, 49√7 = 7^x, ( writing 49 as 7^2, and sending it to the R.H.S )

√7 = 7^x/7^2 ( By rules of exponents, we get the R.HS as 7^(x - 2))

And, the LHS can be written as 7^(1/2)

So.. 7^(1/2) = 7^(x - 2)

Hence, 1/2 = x - 2

"x = 5/2"
