Question

please say answer very fast​

Answer 1

The given expression:

= - a

We have to write the exponential form of the given expression.

Solution:

∴  = - a

∵ 347 = 7 × 7 × 7 =

= - a

Using the logarithm identity:

⇒  = - a

⇒ -  = - a

⇒  = a

⇒  =  [ ∵ Using the logarithm property]

⇒  = 1

⇒  = 1

⇒  - 1 = 0

∴ The exponential form of  = - a is  - 1 = 0 or,  =  7a=7^3
