h)5^12(3+2)=5^12 × 5 = 5^13
i)3^19(3-2)=3^19

Answer 2

6)

a)  6 + 5 x 6 = 6 x ( 1 + 5 ) = 6 x 6 = 6²

b)   2⁴⁺¹ + 6 x 2⁴ = 2⁴ x ( 2 + 6 ) = 2⁴ x 8 = 2 ⁴ x 2³ = 2⁷

c)  3⁹ + 6 x 3⁸ = 3⁸ x ( 3 + 6 ) = 3⁸ x 9 = 3 ⁸ x 3² = 3 ⁽ ⁸ ⁺ ² ⁾ = 3¹⁰

d)   2¹⁰ - 2⁹ =  2⁹ x ( 2 - 1 ) = 2 ⁹ x 1 = 2⁹

e)   3¹⁰ + 2 x 3¹⁰ = 3 ¹⁰ x ( 1 + 2 ) = 3¹⁰ x 3 = 3¹¹

f)   3 x 2²⁰ + 2²⁰ = 2²⁰ x ( 3 + 1 ) = 2²⁰ x 4 = 2²⁰ x 2² = 2²²

g ) 7 x 3¹⁵ +  20 x 3¹⁵ = 3¹⁵ x ( 7 + 20 ) =  3¹⁵ x 27 = 3¹⁵ x 3³ = 3¹⁸

h )  3 x 5¹² + 2 x 5¹² = 5¹² x ( 3 + 2 ) = 5¹² x 5 = 5¹³

i )  3²⁰ - 2 x 3¹⁹ = 3¹⁹ x ( 3 - 2 ) = 3¹⁹ x 1 = 3¹⁹
