Answer 1
#sqrt162 + 11sqrt243 -7sqrt128 + sqrt192#
#=sqrt(2*9^2) + 11sqrt(3*9^2) -7sqrt(2*8^2) + sqrt(3*8^2)#
#=9sqrt2 + 99sqrt3 -56sqrt2 + 8sqrt3#
#= 107sqrt3 -47sqrt2 #

To simplify the expression sqrt162 + 11sqrt243 - 7sqrt128 + sqrt192, we can simplify each square root individually and then combine like terms.

First, let's simplify the square roots: sqrt162 = 9sqrt2 sqrt243 = 9sqrt3 sqrt128 = 8sqrt2 sqrt192 = 8sqrt3

Now, let's substitute these simplified square roots back into the expression: 9sqrt2 + 11(9sqrt3) - 7(8sqrt2) + 8sqrt3

Next, let's simplify the coefficients: 9sqrt2 + 99sqrt3 - 56sqrt2 + 8sqrt3

Now, let's combine like terms: (9sqrt2 - 56sqrt2) + (99sqrt3 + 8sqrt3) -47sqrt2 + 107sqrt3

Therefore, the simplified expression is -47sqrt2 + 107sqrt3.
