64/81=(8/9) what is the exponent
Hi
x = exponent
64 = 8·8 = 8^2
81 = 9·9 = 9^2
64/81 = 8^2/9^2 = (8/9)^2
(8/9)^2 = (8/9)^x
x = 2
Answer: The exponent is 2
Answer:
2 is the exponent
Step-by-step explanation:
Given is an equation as
\(\frac{64}{81} =(\frac{8}{9} )^m\)
and we have to find the exponent m
Since 64 and 81 are prime to each other we cannot simplify the fraction.
We find that both 64 and 81 are perfect squares of 8 and 9 respectively
Hence we write
\(\frac{64}{81} =(\frac{8^2}{9^2} )\\\frac{64}{81} =(\frac{8}{9} )^2\)
Comparing m =2
