For this case we must find an expression equivalent to:
![\sqrt [7] {x} * \sqrt [7] {x} * \sqrt [7] {x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B7%5D%20%7Bx%7D%20%2A%20%5Csqrt%20%5B7%5D%20%7Bx%7D%20%2A%20%5Csqrt%20%5B7%5D%20%7Bx%7D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So, rewriting the given expression we have:
To multiply powers of the same base we put the same base and add the exponents:
Answer:
Option 1
Answer:
dam
Step-by-step explanation:
Answer: 228 yds^2
Step-by-step explanation:
Surface Area= 2 (L x W) + (L x H) + (W x H)
2×(6×4 + 6×9 + 4×9) = 228
Answer: 125.6 ml
Step-by-step explanation:
V = (3.14) (2^2) (10)
V = (3.14) (4)(10)
V= 125.6 cm^3
1 cubic centimeter = 1 milliliter
<span>Let the extension of the length and width be x.
The new dimensions are: Length = 8+x
Width =3+x
Area = 104 ft squared
Area of a rectangle = Length x Width
Therefore,
(8+x)(3+x) = 104
x^2 +11x +24=104
x^2 +11x +24-104=0
x^2 +11x-80=0
Factorize using splitting the middle term method.
X^2 +16x-5x-80=0
x(x+16)-5(x+16)=0
(x-5)(x+16)=0
either x-5 = 0 or x+16=0
x=5 or x=-16
length and width measure cannot be negative.
Therefore, the extension of the length and width is 5 feet each.</span>
