Answer:

4x^{5}

Step-by-step explanation:

The given expression is 4\sqrt{x^{10}}

We have to simplify the given expression

4\sqrt{x^{10}}=4\sqrt{(x)^{5}(x)^{5}}

= 4\sqrt{(x^{5})^{2}}

= 4[(x^{5})^{2}]^{\frac{1}{2}}

= [(x^{5})^{2\times \frac{1}{2}}] [Since [a^{m}]^{n}=a^{m\times n}

= 4x^{5}

Therefore, the expression equivalent to the given expression will be 4x^{5}

Find the first four terms of the sequence<br> An=2a n-1,where a1=3
yKpoI14uk [10]

The first four terms of the sequence are 3 , 6 , 12 , 24

Step-by-step explanation:

We need to find the first four terms of the sequence a_{n}=2a_{n-1}

where a_{1}=3 to find them do that

  • Substitute n by 2 in the rule to find a_{2}
  • Substitute n by 3 in the rule to find a_{3}
  • Substitute n by 4 in the rule to find a_{4}

∵ a_{n}=2a_{n-1}

- Substitute n by 2 to find the 2nd term

∴ a_{2}=2a_{2-1}

∴ a_{2}=2a_{1}

∵ a_{1}=3

∴ a_{2}=2(3)

∴ a_{2}=6

- Substitute n by 3 to find the 3rd term

∴ a_{3}=2a_{3-1}

∴ a_{3}=2a_{2}

∵ a_{2}=6

∴ a_{3}=2(6)

∴ a_{3}=12

- Substitute n by 4 to find the 4th term

∴ a_{4}=2a_{4-1}

∴ a_{4}=2a_{3}

∵ a_{3}=12

∴ a_{4}=2(12)

∴ a_{4}=24

The first four terms of the sequence are 3 , 6 , 12 , 24
