Question

urgentt!! Cu ce numere trebuie inmultite numerele urmatoare pentru a obtine patrate perfecte: 3(a la puterea 2) ; 5(a la puterea 4); 8(a la puterea 2 ori b la puterea 2) ; 4(ab la puterea 8) ; 36(a la puterea 4 ori b la puterea 3) ; 27( a la puterea 5 ori b ); 24(ab la puterea 4) ; 72( a la puterea 3 ori b la puterea 3 )

Answer 1

3(a^2)
3(a^2) × 3=(3a)^2
 5(a^4)
5(a^4) × 5=(5a^2)^2
 8(a^2 × b^2)
 8(a^2 × b^2) x2 = 16×(a^2 × b^2)=2^4×(a^2 × b^2)=(2^2×a×b)^2
 4(ab^8)
4(ab^8) ×a=2^2×a^2×b^8 =(2×a×b^4)^2
36(a^4 × b^3)
36(a^4 × b^3) ×b=(6×a^2×b^2)^2
27( a^5 × b )
27( a^5 × b ) ×3×a×b=(3^2×a^3×b)^2
24(ab^4)
24(ab^4)x 2×3×a=(2^2×3×a×b^2)^2
72( a^3 × b^3 )
72( a^3 × b^3 ) × 2 ×a×b=(2^2×3×a^2×b^2)^2
