    Multiply the exponent of . by 2giving The answer is .x^2 evaluates to Multiply r and 2 Multiply r and 1 The r just gets copied along. The answer is r r 2*r evaluates to 2r Multiply o and 2r Multiply the o and r Multiply o and r The o just gets copied along. The r just gets copied along. The answer is or or 2*r*o evaluates to 2or Multiply o and 2or Multiply the o and or Multiply o and or Combine the o and o by adding the exponents, and keeping the o, to get The r just gets copied along. The answer is 2*r*o*o evaluates to Multiply t and Multiply the t and Multiply t and The t just gets copied along. The just gets copied along. The r just gets copied along. The answer is 2*r*o*o*t evaluates to Multiply 5 and Multiply 1 and The t just gets copied along. The just gets copied along. The r just gets copied along. 2*r*o*o*t*5 evaluates to Multiply x and Multiply the x and Multiply x and The x just gets copied along. The t just gets copied along. The just gets copied along. The r just gets copied along. The answer is 2*r*o*o*t*5*x evaluates to .x^2+2*r*o*o*t*5*x evaluates to The answer is .x^2+2*r*o*o*t*5*x+ evaluates to The final answer is
