Answer 1

Pls refer to the above attachment for the solution of your question.

Imp points used while solving this q.=>

1. a^n×a^m = a^(n+m)

2.a^n/a^m = a^(n-m)

3. Expressing big no.s like 27 & 9 in powers of3.

Answer 2

Answer:b) a¹⁰b⁻²c⁶d⁻⁵

b)3⁻²

Step-by-step explanation:

b)a⁴xb⁻¹⁰xc³xd⁻³/a⁻⁶xb⁻⁸xc⁻³xd²

=a⁴⁺⁶xb⁻¹⁰⁺⁸xc³⁺³xd⁻³⁻²=a¹⁰b⁻²c⁶d⁻⁵

b)3²⁽ⁿ⁺⁶⁾x9²ⁿ⁻⁷/27²ⁿ

=3²ⁿ⁺¹²x((3)²)²ⁿ⁻⁷/((3)³)²ⁿ

=3²ⁿ⁺⁴ⁿ⁺¹²⁻¹⁴/3⁶ⁿ

=3⁶ⁿ⁻⁶ⁿ⁻²=3⁻²

Hope it helps you
