If `2^5` is multiplied by `2^3`, what power of 2 do we get?

If 2^10 is doubled, what power of 2 do we get?

The variance of 20 observations is '5 .' If each observation is multiplied by 2, find the new variance of the resulting observations.

1/2+1/4+1/8=1-1/8 If we multiply the numbers on either side by 8 , we get

If 2 is added to the denominator of a fraction we get 1/4 . If 1 is added to numerator and simplified we get 2/5 . What is the fraction?

(1)/(2) kilogram of rice is equally filled in 4 bags. If we take 3 such bags together, how much rice do we get? Can you find (2)/(5) of (1)/(3) like this? Can't we find (4)/(9) of (3)/(5) . like this?

how do we do 2.45 xx 3.72 ?

The sum of three numbers is 6. If we multiply third number by 3 and add second number to it, we get 11. By adding first and third numbers, we get double of the second number. Represent it algebraically and find the numbers using matrix method.

What power of 2 we get on dividing 2^5 by 2^3 ?

Second power of 2 is 2^2 3^(rd) power 2^3 The product of 2's 4^(th) power is 2's 6^(th) power. 2^(4)times2^2=2^(4+2)=2^6 like this 2^4/2^2=2^(4-2)=2^2 If we divide 2^(nd) power of 2 with 2^(nd) power of 2, if a number is divided with the same number it is one. 2^2/2^2=2^(2-2)=2^0=1 . Now answer the following question. 10^6/10^5 =____.

Second power of 2 is 2^2 3^(rd) power 2^3 The product of 2's 4^(th) power is 2's 6^(th) power. 2^(4)times2^2=2^(4+2)=2^6 like this 2^4/2^2=2^(4-2)=2^2 If we divide 2^(nd) power of 2 with 2^(nd) power of 2, if a number is divided with the same number it is one. 2^2/2^2=2^(2-2)=2^0=1 . Now answer the following question. 3^2times3^7 =_____
