Question

What is the exact value of the expression 6(sqrt y^8) − (sqrt9y^4) + 3(sqrt y^8) −(sqrty^4) ? Simplify if possible.

Answer 1

\[6\sqrt{y ^{8}}-\sqrt{9y ^{4}}+3\sqrt{y ^{8}}-\sqrt{y ^{4}}\]

Answer 2

sqrty8 =y4
sqrt9y4=3y2
sqrty4=y2

Answer 3

thank you :)

Answer 4

6y4 -3y2 +3y4

Answer 5

-y2

Answer 6

no, it is positive :) u were right the 1st time

Answer 7

=9y4-4y2

Answer 8

yes this -y2 is continue

Answer 9

of last line

Answer 10
