Answer 1

a)   2¹⁷ x 2²¹ = 2 ⁽ ¹⁷ ⁺ ²¹ ⁾ = 2³⁸

b)   3⁴⁵ x 3⁸⁷ x 3⁵⁵ = 3 ⁽ ⁴⁵ ⁺ ⁸⁷ ⁺ ⁵⁵ ⁾ = 3¹⁸⁷

c)   7¹⁹ x 7⁸³ x 7 = 7 ⁽ ¹⁹ ⁺ ⁸³ ⁺ ¹ ⁾ = 7¹⁰³

d)   2⁴⁷ : 2³⁹ = 2 ⁽ ⁴⁷ ⁻ ³⁹ ⁾ = 2⁸

e)  5¹⁰⁸ : 5⁷² = 5 ⁽ ¹⁰⁸ ⁻ ⁷² ⁾ = 5³⁶

f)  2³⁷ x 2⁴⁷ : 2⁵⁰ = 2 ⁽ ³⁷ ⁺ ⁴⁷ ⁻ ⁵⁰ ⁾ = 2³⁴

g)   ( 10¹² ) ¹⁵  = 10 ¹² ˣ ¹⁵ = 10¹⁸⁰

h)   ( 2¹⁷ ) ⁸ x 2³¹ = 2 ⁽ ¹³⁶ ⁺ ³¹ ⁾ = 2 ¹⁶⁷
