The value of x is "- 1".

Step-by-step explanation:

We have,

49\times 7^{x} =343^{\dfrac{1}{3} }49×7

x

=343

1

To find, the value of x = ?

∴ 49\times 7^{x} =343^{\dfrac{1}{3}}49×7

x

=343

⇒ 7^{2} \times 7^{x} =(7^{3} )^{\dfrac{1}{3}}7

⇒ 7^{2+x} =(7^{3\times \dfrac{1}{3}})7

2+x

=(7

[ ∵ a^{m} \times a^{n} =a^{m+n} and (a^{m} )^{n} =a^{mn}a

⇒ 7^{2+x} =7^{1}7

2+x

=7

Equating the power of 7, we get

∴ 2 + x = 1

⇒ x = 1 - 2 = - 1

Hence, the value of x is "- 1".
