Answer 1

Answer:

The answer is 7⁷ .

Step-by-step explanation:

Given that Indices Law is,

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

So the correct working and steps are :

$\frac{ {7}^{4} }{ {7}^{ - 3} }$

$= {7}^{4 - ( - 3)}$

$= {7}^{4 + 3}$

$= {7}^{7}$

Andre make a mistake in,

${7}^{4 - 3}$

Answer 2

Answer:

He subtracted 3 from the exponent 4 instead of subtracting -3.

Step-by-step explanation:

Correct answer is 7^7:-

7^4 / 7^-3

= 7^(4 - (-3))

= 7^(4+3)

= 7^7.
