Choose the polynomial written in standard form.

x2 + 4x4 + 10x6

x4 + 4x3 + 10x

x7 + 4x3 + 10x4

x6 + 4x3 + 10x7

Step-by-step explanation:

A polynomial written in decreasing order of the degree of its monomials ( or single term ) is called its standard form,

In polynomial,

,

Degrees are written in increasing order,

⇒ It is not written in standard form,

In polynomial,

,

Degrees are written in decreasing order,

⇒ It is written in standard form,

In polynomial,

,

There is no order of degrees,

⇒ It is not written in standard form,

step-by-step explanation:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
