can any body tell me simple way to find 2^43 ( two raise to the power 43), i need a simple formula?

Question

i want a formula were by i need not have to multiply 2*2*2*2....43 time , as that is time consuming,, is ther a formula

Answer 1

2^43 = 2 * 2^42 = 2 * 4^21 = 2*4 * 16^10 = 8 * 256^5 = 8*256 * 256^4 = 2048 * 65536^2. If you want to take the time to calculate 65536*65536, and then multiply this by 2048, you'll have 2^43.

Answer 2

Assume that
2^43 = x
taking log on both sides
log (2^43) =Log x -------(1)

we have a formula log (x^y)= y* log x
using this...
Equation (1) canbe rewritten as
43 * log 2 = log x
we know log 2=0.3010(From tables or using a calculator) (BETTER MEMORISE THESE VALUES IT WILL HELP U A LOT)
ie)43 * 0.3010 = log x
12.9443 = log x
ie)log x = 12.9443
hence x = antilog(12.9443)
x = value

This is the answer.

Step to find Antilog.
Antilog of 12.9443


Separate the mantissa from the characteristic
12 and .9443


Determine the antilog of
.9443

If you don't find a mantissa in the table that is .9443 find the one that comes closest. In my four place log table the closest that to .9443 that it has is one that is .9443. Move from there to the left to the front of the row where we find the digits


Moving your finger from the .9443 upward to the top of the column gives the single digit


So the Antilog (12.9443) = Z X 10^43 = value

Answer 3

With natural logarithms:

Ln x = 43 * Ln 2

Ln x = 43 * 0.6931471

Ln x = 29.805329

x = 8.7961 x 10^(12)
.

Answer 4

They seem so simple until you really think about them... a baby's smile, a child's wonder, a flower growing wild, love and hugs, friends, nature, a sunrise... and so much more. They are there, they continue to be there... they seem simple in the idea.. but never are they simple when they bring such joy to my heart.

Answer 5

on paper unfortunately not
you can on a calculator eg. 2^43 on calc- press 2, ^, 43,=
you probably already know this..lol
hope it helps anyway

Answer 7

let x=2^43
logx=43log2
logx=43x0.3010
calculate it n find out antilog of X, it ll b answer

Answer 8

go see the 11 class mathematics, its permutation and combination.

Answer 9

YOU CAN SIMPLY USE PERMUTATION AND COMBINATION INSTEAD OF USING RAISED POWERS.
