${2}^{ x} = 8 \\ {3}^{x} = 27 \\ {5}^{x} = 625 \\ {4}^{x} = 64 \\ {23}^{x} = 1 \\ {11}^{x } = 121$
Plzzzzz​

Answer 1

2*= 8 => x= 3 ( 2^3= 8)
3*= 27 => x= 3 (3^3= 27)
5*= 625=> x= 4 ( 5^4= 625)
4*= 64=> x= 3 (4^3= 64)
23*= 1 => x= 0 (23^0= 1)
11*= 121=> x= 2 (11^2= 121)

Answer 2

Explicație pas cu pas:

${2}^{x} = 8 \iff {2}^{x} = {2}^{3} \implies x = 3$

${3}^{x} = 27 \iff {3}^{x} = {3}^{3} \implies x = 3$

${5}^{x} = 625 \iff {5}^{x} = {5}^{4} \implies x = 4$

${4}^{x} = 64 \iff {4}^{x} = {4}^{3} \implies x = 3$

${23}^{x} = 1 \iff {23}^{x} = {23}^{0} \implies x = 0$

${11}^{x } = 121\iff {11}^{x} = {11}^{2} \implies x = 2$
