Step-by-step explanation:
Given expression:
13) 
15) 
Write the expressions in radical form.
Solution:
For an expression with exponents as fraction like

the numerator
represents the power it is raised to and the denominator
represents the nth root of the expression.
For an expression with exponents as negative fraction like

We take the reciprocal of the term by rule for negative exponents.
So it is written as:

using the above properties we can write the given expressions in radical form.
13) 
⇒
[Using rule of negative exponents]
⇒
[writing in radical form]
15) 
⇒
[Since 2nd root is given as
in radical form]
Answer:
(x - 4)(x + 4)(x - 1)(x + 1)
Step-by-step explanation:
Given
- 17x² + 16
Use the substitution u = x², then
u² - 17u + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the u- term (- 17)
The factors are - 16 and - 1, then
u² - 17u + 16
= (u - 16)(u - 1) ← replace u by x²
= (x² - 16)(x² - 1) ← both factors are difference of squares
= (x - 4)(x + 4)(x - 1)(x + 1)
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2
