Answer 1

Answer:

81 0 . 16 × 81 0 . 09 = 81 0 . 16 + 0 . 09 using , x n + x m = x n + m = 81 0 . 25 = 3 4 × 0 .

Step-by-step explanation:

Answer 2

Answer:

By law of exponents (a^n × a^x =a^(n+x))

= 81^(0.16+0.09)

= 81^(0.25)

= (3^4)^0.25

= (81=3×3×3×3=3^4)

= 3^(4×0.25)

= (a^n )^x = a ^nx

= (3)^1
