Question

tim x:

45\(x^0\)-8x = 13

Answer 1

\(\Leftrightarrow45-8x=13\left(because45x^0=45.1=45\right)\)

\(\Leftrightarrow8x=32\)

\(\Leftrightarrow x=4\)

Answer 2

= 45-8x=13(because45x mũ 0=45.1=45

=8x=8.4=32

= x=4

tick mình đi

Answer 3

\(45x^0\) - 8x =13

45 - 8x = 13

8x = 45-13

8x = 32

x = 32 : 8

x = 4

Vậy x =4
