Question

Find the value of 3^x+3^x+3^x=162

Answer 1

We have:

$3^x+3^x$ = 162

We have to find, the value of x is:

Solution:

∴ $3^x+3^x$ = 162

Taking $3^x$ as common in L.H.S., we get

⇒ $3^x$ (1 + 1) = 162

⇒ $3^x$ (2) = 162

⇒ $3^x$ = $\dfrac{162}{2}$

⇒ $3^x$ = 81 [ ∵ 81 = 3 × 3 × 3 × 3]

⇒ $3^x$ = $3^4$

⇒ x = 4

Thus, the value of "x is equal to 4".
