Question

If a=2^-2 , b=2^-3 ,c = 2^-4 2^-2 then find a^3 +b^3+c^3​

Answer 1

a = $2^{-2}$  ,  b=$2^{-3}$ , c = $2^{-4}* 2^{-2}$

Find = a³ + b³ + c³

value of a = $2^{-2}$

                 = -2 * -2 = 4

value of b = $2^{-3}$

                 = -2 * -2 * -2 = -8

value of c = $2^{-4} *2^{-2}$

                 = -2 * -2 * -2 * -2  *  -2 *-2

                 =  16 * 4 = 64

now we have the values of a , b , and c .

a³ + b³ + c³

4³ + (-8)³ + 64³

64 + (-512) + 262,144

262,144+ 64 - 512

ANSWER = 261,696
