givi [52]

Answer:

${n}^{1\frac{1}{2}}{p}^{2}$

Step-by-step explanation:

According to the Definition of Rational Exponents, use this formula to rewrite this as an exponential expression:

$a^{\frac{m}{n}} = \sqrt[n]{a}^{m}$

NOTE: Since we have exponents in our radical, we have to multiply all exponents by one-half, since raising something to its half power is the exact same as taking the square root of something:

$[{n}^{3}{p}^{4}]^{\frac{1}{2}} = {n}^{1\frac{1}{2}}{p}^{2}$

* Do not forget to remove the radical in the beginning because you are once again, rewriting this as an exponential expression.

I am joyous to assist you anytime.

Solve the system of linear equations by substitution. Check your solilution. y=x+3 y=5x-5

Margaret [11]

9514 1404 393

Answer:

(x, y) = (2, 5)

Step-by-step explanation:

Substitute the expression for y in the second equation into the first equation:

5x -5 = x +3

4x = 8 . . . . . . add 5-x to both sides

x = 2 . . . . . . divide by 4

y = 2+3 = 5 . . . substitute for x in the first equation

The solution is (x, y) = (2, 5).
