(25 la putrea a 2 •5la puterea 4 totul la a 3:5 la puterea 22-2la a 2la 2

Answer 1

(25^2×5^4)^3 ÷5^22-2^2^2
=[(5^2)^2 ×5^4]^3 ÷5^22-2^4
=(5^4×5^4)^3 ÷5^22 -16
=(5^8)^3 ÷5^22 -16
=5^24÷5^22 -16
=5^2 -16
=25-16
=9
P.S. ^=la putere

Answer 2

(25²ₓ5⁴)³:5^22-₍2²₎² =(₍5²₎²ₓ5⁴)³:5^22-2⁴= (5⁴ₓ5⁴)³:5^22-2⁴= ₍5⁸₎³:5^22-2⁴= 5^24:5^22-2⁴=5²-2⁴=25-16=9=3²
