Evaluate sqrt7x (sqrt x-7 sqrt7) Show your work.
sqrt(7)*sqrt(x)-sqrt(7)*7*sqrt(7)
sqrt(7*x)-7*sqrt(7*7)
sqrt(7x)-7*sqrt(7^2)
x*sqrt 7x-49*x
^^^ would this be my final answer?
sqrt(7)*sqrt(x)-sqrt(7)*7*sqrt(7)

Assuming you meant:
√7 x(√x - 7√7)
= x√(7x) - 49x
brackets are important here
e.g √(7x) vs √7x , the last one is (√7)x
√7 x(√x - 7√7)
= x√(7x) - 49x
brackets are important here
e.g √(7x) vs √7x , the last one is (√7)x
