Question

(5x - 3) ⁵ -10⁰ =31

giúp mk nha

Answer 1

(5x-3)^5=31+1

(5x-3)^5=32

(5x-3)^5=2^5

Suy ra 5x-3=5

5x=8

x=8/5

Answer 2

(5x-3)^5-10^0=31

-> (5x-3)^5-1=31

-> (5x-3)^5=32

-> (5x-3)^5=2^5

-> 5x-3=2->5x=5->x=1

Answer 3

(5x - 3)⁵-1=31

(5x - 3)⁵=31+1

(5x-3)⁵=32

(5x-3)⁵=2⁵

=>5x-3=2

5x=2+3

5x=5

x=5:5

x=1

Answer 4

(5x-3) mũ 5-10 mũ 0=31

(5x-3)mũ 5-1=31

(5x-3)mũ 5=31+1

(5x-3)mũ 5 =32

=5x mũ 5-3 mũ 5=2 mũ 5

5x-3=2

5x=2+3

5x=5

x=5:5

x=1

nếu có các số mũ giống nhau thì ta bỏ các số mũ nhé!
