1. Do the following calculations in R

(5*4)^(4*5)-56
## [1] 1.048576e+26
23-1*(8-12)
## [1] 27
56/8*(3+4)
## [1] 49
45-5*8+(8+9)
## [1] 22

2. Create the following vectors a, b, and c

  1. 2,5,6,7
a <- c(2,5,6,7)
a
## [1] 2 5 6 7
  1. 1,0,9,8
b <- c(1,0,9,8)
b
## [1] 1 0 9 8
  1. 6,5,8,3
c <- c(6,5,8,3)
c
## [1] 6 5 8 3
