Nady [450]

Answer:-288

Step-by-step explanation:

Given

First term $a_0$ is common for both AP and GP

For AP

$a_2=4=a_0+2d$ ---1

$a_4=12=a_0+4d$ ----2

From 1 & 2 we get

d=4

$a_0=-4$

$a_{10}$ for AP

$a_{10}=a_0+10d=-4+10\times 4=36$

For GP

$4=a_0r^2$ ----3

$12=a_0r^4$ ----4

From 3 & 4 we get

$3=r^2$

$r=\sqrt{3}$

$a_0=\frac{4}{3}$

For $a_{10}=\frac{4}{3}\times 3^5=324$

$AP_{a_{10}}-GP_{a_{10}}=36-324=-288$

zhuklara [117]

Answer:

Step-by-step explanation:

First give it as a product of prime factors. Divide 9801 with prime numbers. The first picture divides 9801 fron prime numbers. Prime numbers are 2,3,5,7, 11. We can only divide using 3 and 11. So we get 3⁴ and 11². The second picture shows how I got the square root of 9801. Square root is ½. So we multiply each power with ½ so we finally get 99. You can recheck for yourself using a calculator. It is 99.
