Question

solve the following by using laws exponents 3⁷/3⁸​

Answer 1

Answer:

${3}^{7} \div {3}^{8}$

in division the powers are subtracted .

${3}^{ - 1}$

when the power is negative the number is reciprocated.

the correct answer is 1/3

Answer 2

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Firstly :-

$\frac{ {3}^{7} }{ {3}^{8} } = {3}^{7} \ \times {3}^{ - 8}$

Now , Since the value of

${3}^{8}$

went up it changes to

${3}^{ - 8}$

So now taking 3 common

${3}^{7 - 8 = {3}^{ - 1} } \\ = \frac{1}{3}$

Now here we took the formula that {a}^{b} × {a}^{c} = {a}^{b+c}
