Question

(5)³n+²×(5)³n–²=(5)n+¹⁰ find 'n'​

Answer 1

Answer:

(5)^3n+2+3n-2=5^n+10

5^6n=5^n+10

6n=n+10.(a^m=a^n then m=n).

5n=10

n=2.

Answer 2

Step-by-step explanation:

Well:

125n+2×125n-2=5n+10

+2 nd -2 cancel we get

125n×125n= 5n+10

15625n=5n+10

-5n on both sides

15625n-5n= 10

15620n=10

÷ing 15620 on both sides we get.

n= 10/15620

n=0.00064
