Answer:

Simplest form is a^{\frac{2}{15} }.

Step-by-step explanation:

Given : \frac{\sqrt[5]{a^{4}}}{\sqrt[3]{a^{2}}}.

To find : Which of the following is the simplest form of this expression?

Solution: We have given :

\frac{\sqrt[5]{a^{4}}}{\sqrt[3]{a^{2}}}

By the radical rule \sqrt[a]{b^{c} } = b^{\frac{c}{a}},

Then

\frac{\sqrt[5]{a^{4}}}{\sqrt[3]{a^{2}}}  = \frac{a^{\frac{4}{5}}}{a^{\frac{2}{3}}}.

⇒a^{\frac{4}{5} -\frac{2}{3}}.

⇒ a^{\frac{12-10}{15} }.

⇒ a^{\frac{2}{15} }.

Therefore, Simplest form is a^{\frac{2}{15} }.

The numerator could be written a⁴/⁵

The denominator could be written a²/³


Now solve  ( a⁴/⁵) / (a²/³) ==> a⁽⁴/⁵ ⁻²/³)  = a⁽²/¹⁵)

This is the simplest way

the nth term of a sequence is given by an²+bn where a and b are integers the 2nd term of the sequence is 2 4th term of the seque
stealth61 [152]

Answer:

54

Step-by-step explanation:

Tn = an²+bn

T2 = a2²+2b

2 = 4a +2b

Multiply all through by 2

4 = 8a +4b

4b = 4-8a

T4 = a4² + 4b

20 = 16a +4b

4b = 20-16a

4-8a = 20-16a

16a -8a = 20-4

8a = 16

a = 16/8 = 2

4b = 4-8a = 4-8(2) = 4-16 = -12

b = -12/4 = -3

T6 = a6² + 6b

T6 = 2(36) + 6(-3) = 72 -18 = 54

N76 [4]

Answer:

7 feet

Step-by-step explanation:

sqrt(4.5^2 + 5.3^2) = hypotenuse

sqrt(48.34) = hypotenuse

6.95269732 = hypotenuse

round to nearest tenth

7 feet = the length of the hypotenuse
