Answer 1

Answer:

1) 9.6 * 10^6 = 9600000

 13.8 * 10^4 = 138000

9600000+138000 = 9738000 = 9.738 * 10^6

2) 81^x+1 =

   3^4(x+1)

=  3^4x+4

3^x+1 = 1/3^4x+4

1 = 3^x+1 * 3^4x+4

1 = 3^ x + 1 + 4x + 4

1 = 3^ 5x + 5

3^0 = 1

hence

5x + 5 = 0

5x = -5

x = -1

Answer 2

Answer:

1st question

9600000+1380000

=1,98,00,000

=1.98×10⁵

2nd question

=3^x+1=1/(3⁴)^x+1

=3^x+1=1/3^4x+4

=3^x+1=3^-4x+4

bases are same then powers will be added

=x+1 = 4x+4

=x-4x = -1+4

= -3x = -3

= x = -3/-3

= x = 1
