Question

Solve (5by6) raised to -5 x (5by6) raised to -11 = (5by6) raised to 8x

Answer 1

Answer:

x = -3/4

Step-by-step explanation:

We have:

(5/6)^5 × (5/6)^-11 = (5/6)^8x

= (5/6)^-11 + 5 = (5/6)^8x

(Using the rule x^a × x^b = x^(a + b))

Comparing both sides

8x = 5 - 11

= 8x = -6

= x = -3/4
