Question

If (x)⁶ = (49)³, then x is give me answer​

Answer 1

Answer:

Answer:

Given

(9/7)3 × (49/81) (2x-6) = (7/9)9

We know that the reciprocal of (9/7)3 is (7/9)-3

(49/81)2x-6= ((7/9)2)(2x-6)

(7/9)-3 × ((7/9)2)(2x-6) = (7/9)9

All the bases are the same, hence equating the powers we get,

-3 + 4x – 12 = 9

4x = 9 +15

4x = 24

x = 6

Answer 2

${x}^{6} = {(49)}^{3}$

$6x = 1,17,649$

$x = \frac{1,17,649}{6}$

$x = 1,9608.16$
