What is ( 2 ^8 x 5^-5 x 19^0) ^-2 x ( 5^-2 / 2^3 ) ^4 x 2^28

(2^8x5^-5x19^0)^-2 x (5^-2/2^3)^4 x 2^28

(256x0.00032x1)^-2 x (0.04/8)^4 x 2^28

0.08192^-2 x 0.005^4 x 268,435,456

149.0116119384766 x 0.000000000625 x 268,435,456

0.000000093132257 x 268,435,456

= 25

6 and 7 are the two consecutive whole numbers between which square root of 38 lie

Step-by-step explanation:

There are two methods to solve this problem

First method:

In this method we will find the square root of 38.

square root of 38 is 6.16

and 6.16 lies between 6 and 7

Therefore 6 and 7 are the two consecutive whole numbers between which square root of 38 lie.

Second method:

In this method we will find the square of the numbers which is close to 38

so there are two numbers 36 and 49 which are squares of 6 and 7 respectively.

therefore square roots of all the numbers which lie between 36 and 49 lie between 6 and 7
