Question

(-6)^5 X(-6) ^3-m = (-6)^3​

Answer 1

Answer:

Let m = n

(-6)⁵ x (-6)³⁻ⁿ = (-6)³

(-6)⁵⁺³⁻ⁿ = (-6)³

= 8 - n = 3

∴ n = 5 = m

Answer 2

Answer:

5

Step-by-step explanation:

${ - 6}^{5} \times { - 6}^{3 - m } = { - 6}^{3} \\ by \: laws \: of \: exponents \: {a}^{m} \times {a}^{n} = {a}^{m + n } \\ applying \: the \: law \: we \: get \\ ( { - 6})^{5 + 3 - m} = { - 6}^{3} \\ = 5 + 3 - m = 3 \\ = 8 - m = 3 \\ = - m = 3 - 8 \\ = - m = - 5 \\ = m = 5$
