Question

Andre was trying to write 7⁴/ 7⁻³ with a single exponent and wrote 7⁴/ 7⁻³ = 7⁴⁻³ = 7¹. Explain to Andre what his mistake was and what the answer should be.

Answer 1

Answer:

His mistake was that he removed the fraction and instead he used $7^4^-^3 =7^1$. He should've kept the fraction to make the answer right.
