Question

Find the solution set of the following equations and also verify the answer: 10√x+20=100​

Answer 1

Answer:

10√x+20=100

10√x=100-20

10√x=80

√x=80/10=8

√x=8

x=8²

x=64

verification:

x is taken as 64

10√64+20=100

10(8)+20=100

80+20=100

100=100

lhs=rhs hence proved

Answer 2

10rootx+20=100
10rootx=100-20
10rootx=80
Rootx=80/10
Rootx=8
X=8^2
X=64
