Question

The value of n when 7²ⁿ+³ = 1 is
pls tell quick​

Answer 1

Answer:

(-3/2)

Step-by-step explanation:

As far as we know there is no natural number n such that this equation will be equal to 1

Thus, there remains only 1 solution which is 7 power 0=1

So----->

2n+3=0

2n = -3

n=  -3/2  OR -1.5

Hope you understood!

Answer 2

Answer:

answer is -3/2

Step-by-step explanation:

firstly we'll multiply both sides by 7 to make the bases same

7×7^2n+3=1×7

we know that if bases are same in multiplication then we will add the power

7^2n+3+1=7

now ,we'll cut 7 from both sides because its common

2n+4=1

2n=1-4

2n= -3

n= -3/2
