Question 887219: Simplify - Step by Step
sqrt(7)+3,sqrt(98)
sqrt(7)+3,sqrt(98)
21√2 + √7
S-By-S
sqrt(7) +3, 7sqrt(2)
sqrt(7)+21sqrt(2)
2^2 =4 3^2 = 9
sqrt(7)= sqrt(1)sqrt(7)
sqrt(1) = 1
3sqrt(98)
sqrt98 = sqrt(1) sqrt(98)
sqrt98 = sqrt(2) sqrt(49)
sqrt98 = sqrt(7) sqrt(14)
root = 49
sqrt(98)= sqrt(49) sqrt(2)
sqrt(49)=7
3sqrt(98)= (3x7) sqrt(2)
3sqrt(98)= 21 sqrt(2)
answer 21sqrt(2)+ sqrt(7)
when i try this in the grader. wrong answer
Thank You
V.
