Nhe em, 5.9=45 copy all 0 cua em la dc :))

x + 532 = 1104

        x = 1104 - 532

        x = 572

A)  4. ( 16-3^x ) = 52

16 - 3^x = 52 : 4

16 - 3^x = 13

3^x = 16 - 13

3^x = 3

3^x = 3¹

=> x = 1

Vậy x = 1

B) ( 5^x + 124 ) = 25²

5^x + 124 = 625

5^x = 625 - 124

5^x = 501

=> x \(\in\varnothing\)

Vậy x \(\in\varnothing\)
