Question

Ex 8!DAU COROANA!!VA ROG

Answer 1

a) 5⁴⁶ = 5²³ ˣ ² = ( 5²³ )² ==> patrat perfect

b)  23¹⁰⁰ = 23⁵⁰ ˣ ² = ( 23⁵⁰ )²

c) ( 7⁶ )⁵ = 7³⁰ = 7¹⁵ ˣ ² = ( 7¹⁵ )²

d)  25³⁷ = ( 5² )³⁷ = ( 5³⁷ )²

e)  4⁷⁵ = ( 2² )⁷⁵ = ( 2⁷⁵ ) ²

f)  625 ⁷ = ( 5⁴ ) ⁷ = 5²⁸ = 5¹⁴ ˣ ² = ( 5¹⁴ )²

g)   16 x 25 = 4² x 5² = ( 4 x 5 )² = 20² ==> patrat perfect

h)   2¹⁸ x 3⁶ = ( 2³ )⁶ x 3⁶ = ( 8 x 3 )⁶ = ( 24 ³ )²

i )    25 x 3¹⁸ = 5² x ( 3⁹ )² = ( 5 x 3⁹ ) ²
