Question

${3}^{4 - x} \times {9}^{6 + x} \times {27}^{10 - x} = {81}^{4 + x}$
​

Answer 1

Respuesta:

×=5

Explicación paso a paso:

convierte ambos lados a la misma base.

3^4-× ×3^2(6+×)×3^(10-×)=3^4(4+×)

3^4-×+2(6+×)+3(10-×)=3^4(4+×)

4-×+2(6+×)+3(10-×)=4(4+×)

4-×+12+2×+30-3×=16+4×

46-2×=16+4×

46=16+6×

46-16=6×

30=6×

5=×

×=5
