Question

3x⁴+ 4x²y² + y⁴ how to do it​

Answer 1

• We have a rule in exponents.
• ${y}^{a} + {y}^{b} = {y}^{(a + b)}$
• That is if the bases are same and power are different , We have to add the power and put the the base as it is .

= 3x^4+ 4x^2y^2 + y^4

= 3x^4+ 4x^2*y^6

=7x^6*y^6(now powers are same so add the base )

=7x+y^6
