Describe and correct the error a student made when starting to solve the equation 9^x+3=2^2x-5 8^x+3=2^2x-5 (2^3)^x+3=2^2x-5 2^3x+3=2^2x-5 B A. The student did not convert 8 to the correct power of 2 B. The student should have expressed the initial rational exponent as the sum of two rational exponents C. The student did not distribute 3in(2^3)^x+3 across x+3 D. The student should have divided both sides by 2^2 to simplify the expression.

Describe and correct the error a student made when starting to solve the equation 9^x+3=2^2x-5 8^x+3=2^2x-5 (2^3)^x+3=2^2x-5 2^3x+3=2^2x-5 B A. The student did not convert 8 to the correct power of 2 B. The student should have expressed the initial rational exponent as the sum of two rational exponents C. The student did not distribute 3in(2^3)^x+3 across x+3 D. The student should have divided both sides by 2^2 to simplify the expression.

Answer 1

La respuesta correcta es la opción A. El estudiante no convirtió 8 en la potencia correcta de 2.El error que cometió el estudiante fue al intentar igualar

con

. En lugar de convertir 8 a la potencia correcta de 2, debería haber escrito

como

.La solución correcta sería:

Por lo tanto, la respuesta correcta es la opción A. El estudiante no convirtió 8 en la potencia correcta de 2.
