Simplify this maths problem?
I tried it and got 81/y^3 (0.04y^8)
What have I done wrong?

( 18/y^4 ) x (y^8/25)
( 18/25 ) y^4

y8/y⁴ (81/25 ) = y ^(8-4) * 81/25

(-3/y)^4 (1/5 y^4)^2
= 81y^8 / (25 y^4)
= 81y^4 / 25

81/y^4 (0.04y^8) is ok as far as it goes, but it could go further
81/y^4 * y^8 / 25

First, keep fractions as fractions.
Then your y's can be combined from the first factor and the second factor.
You started correctly, but needed to finish things up.

Do each separately first....
(81/y^4) x (y^8/25) ......now multiply
81y^8 / 25y^4
