High expression is equivalent to ^4 square root x^10

Talja [164]

In order to find which expression is equivalent to $\sqrt[4]{x^{10}},$ simplify all given expressions:

$\sqrt[4]{x^{10}}=x^{\frac{10}{4}}=x^{\frac{5}{2}}=x^{2.5}.$

$x^2(\sqrt[4]{x^2})=x^2\cdot x^{\frac{2}{4}}=x^2\cdot x^{\frac{1}{2}}=x^2\cdot x^{0.5}=x^{2.5}.$

$x^{2.2}.$

$x^3(\sqrt[4]{x} )=x^3\cdot x^{\frac{1}{4}}=x^3\cdot x^{0.25}=x^{3.25}.$

$x^5.$

Therefore,

Kiran scored 223 fewer points in a computer game than Tyler. Kiran scored 409 points. Which equation would Kiran use to determin

LenKa [72]

Answer:

The equation is:

$409 = T - 223$

And the solution is:

$T = 632$

Step-by-step explanation:

Given

Represent Kiran with K and Tyler with T

Kiran score is represented as:

$K = 409$

Also, Kiran scored 223 less than Tyler.

This is represented as:

$K = T - 223$

Substitute 409 for K

$409 = T - 223$

Make T the subject

$T = 409 +223$

$T = 632$
