Question

What is the exact value of the expression the square root of 4 times y to the eighth power. + 6the square root of y squared. − 2the square root of y squared. + the square root of y to the eighth power.? Simplify if possible.

A:5y4 + 3y
B:7y4
C:3y4 + 4y
D:7y6

Answer 1

yes

Answer 2

i guess, i wrote something wrong..

well this is an answer.. i will correct myself..

\[2y ^{4} + 6y - 2y + y ^{4} = 3y ^{y} + 4y\]

option C !!

Answer 3

\[\sqrt{4(y ^{8})} + 6\sqrt{y ^{2}} - 2 \sqrt{y ^{2}} + \sqrt{y ^{8}}\]

this was the right equation..

Answer 4

\[2y ^{4}+6y-2y+y ^{4}\]Combine like terms.
\[3y ^{4}+4y\]

Answer 5

7y^4

Answer 6

You should not attempt to combine unlike terms.
\[y ^{4}\]is not similar to y.

Answer 7

nopes.. terms with same powers are to be added.. with different powers cannot be !!
