The value of `[1^(3) -2^(3) +3^(3) -4^(3) +…+ 9^(3)]` is-

1^(3)-2^(3)+3^(3)-4^(3)+........+9^(3) is equal to

The value of 1- 1/2(3/4) + 1/3(3/4)^(2) -1/4(3/4)^(3) + ... is:

Observe the following pattern :1^(3)=11^(3)+2^(3)=(1+2)^(2)1^(3)+2^(3)+3^(3)=(1+2+3)^(2) Write the next three rows and calculate the value of 1^(3)+2^(3)+3^(3)++9^(3)+10^(3) by the above pattern.

The value of 1-1/2(2/3)+1/3(2/3)^(2)-1/4(2/3)^(3)+... is

The value of 3xx 9^(-3//2) xx 9^(1//2) is

Find the value of (9^-1*5^-3) / 3^-4
